Zachary Snow bf029068af move exprToType utility outside to language module 2021-08-18 13:07:42 -06:00
Zachary Snow 2f860ff220 fix trivial hash collisions
Data.Hashable can produce hashes differing little in their upper bits if
only the last character of the string is changed. Because we were using
the upper bits of the hash in shortHash, this could lead to avoidable
hash collisions. This change includes minor simplification optimizations
which surfaced this collision in the existing struct_ident_scope test.
