Vec considered harmful; use isOneOf instead ( #64 )
...
Vec is heavyweight and really should only be used for I/O and
dynamic indexing. A recurring pattern in uncore is
Vec(const1, const2, const3) contains x
which is nice but has a deleterious effect on simulation copilation
and execution time. This patch proposes an alternative:
x isOneOf (const1, const2, const3)
x isOneOf seqOfThings
I think it's also more idiomatic.
This is just a prototype; I'm not wed to the name or implementation.
