Check that assignment patterns are evaluated in the queue element type
context when they are passed to the queue `push_front()`, `push_back()` and
`insert()` methods.

Check that multi-dimensional packed vector class properties can be emitted,
assigned, and read back through a class object.

Extend the non-blocking event control assignment tests to check that a 0 or
negative repeat value is handled correctly. In this case the assignment
should be executed like a regular non-blocking assignment and the event
control should be ignored.

Check that continuous assignments to unpacked net arrays preserve delay and
drive strength on the generated element drivers.

Check that SystemVerilog net declarations can mix entries with and
without initialization.
Check that in SystemVerilog it is possible to do assignments within net array
declarations.

Check that continuous assignment of an assignment pattern to a single element
unpacked array is accepted. Check that assigning a scalar expression to the
whole unpacked array is rejected for both procedural and continuous
assignments.
Check that a selected element of a single element static unpacked array can be
used in a continuous l-value concatenation.

Check that enum, struct, union and class restricted type parameters are
accepted. Check that mismatched default values and overrides are rejected.

Check that soft packed unions can have members with different widths.
Check that the `soft` qualifier implies `packed` and that nested soft
packed unions use the same representation recursively.
Also check that member bits are right-justified and that assignments to
narrower members leave the MSBs beyond the member bits unchanged. Check
that soft packed unions reject default member values.

Check that each valid `begin_keywords` selector is accepted. Only check
that the selector itself is accepted, in these tests there is no check if
the correct keywords are actually accepted or rejected since that would get
pretty exhaustive.

Check that class objects, dynamic arrays, queues, strings and static
unpacked arrays can not be used as l-value concatenation operands. Check
procedural and continuous assignment concatenations, including single
operand concatenations.

Check that the compiler reports an error for `posedge`, `negedge` and `edge`
event controls on named events. Edge controls can not be used with named
events.
There is already an existing test that checks both `posedge` and `negedge`.
Split it into separate tests so that each invalid event control is checked
independently.

Check that package variables can use explicit static lifetime. Check that
automatic lifetime is rejected for package variables.

Check that string literals can be assigned to byte arrays. Check that
invalid target array types are reported as errors.

Check that drive strength can be specified between the net type and the
data type in a net declaration and that vector gate arrays resolve
strengths correctly.
