78d4fb20c4 inline parameters 
This replaces the current generic syntax for functions and replaces
it with the concept of inline parameters.

This paves the way for the "all structs anonymous" proposal.

Closes #151.

49a4b1b930 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.
