ability to cast explicitly from int to enum
This commit also fixes a bug where pure functions are marked with
the read-only attribute in debug mode. This resulted in incorrect
codegen because calls to read-only functions with unused values
were not generated.
For example, a call to assert() would not be generated if assert
is marked with read-only. Which it *is* marked with in release
mode.
