vhdlpp: Support for integer() function.
...
Note: I could not find any info about the integer() function, but it is
used in the VHDL standard packages (e.g. math_real, see:
http://www.csee.umbc.edu/portal/help/VHDL/packages/mathpack.vhd )
Real numbers are rounded, this is compatible with ModelSim behavior.

find anything that suits better.

vhdlpp: ForLoopStatement emits range boundaries expressions instead of evaluating them.
...
Unfortunately without evaluation it is not possible to warn against
degenerated loops, so it had to be removed.

vhdlpp: Support for std_logic_vector return type in functions.
...
VHDL does not allow to specify the size of returned std_logic_vector,
whereas Verilog requires the size to be known in advance. The size of
the vector is determined by checking the type of expression used in the
return statement.
