types are now valid proc/template/macro params and you can overload over them:
proc foo(T: typedesc) # accept any type
proc foo(T: typedesc{int}) # overload specifically for int
proc foo(T: typedesc{int or float or Callable}) # overload for any type matching the constraints
expr{type} is a param expecting compile time value of the designated type (or type class).
when typedesc or expr params are used with a proc, the proc will be instantiated once
for each unique type/value used as parameter.
This directory contains the test cases. Each test must have a filename of the form: ``t*.nim`` Each test can contain a spec in a ``discard """"""`` block. The folder ``rodfiles`` contains special tests that test incremental compilation via symbol files. The folder ``dll`` contains simple DLL tests.
