NimVM generic procs that take anonymous tuples gives nil access error.

[beef331]

When using T: typedesc and passing a anonymous tuple the NimVM is incapable of running the code

Example

static:
  proc a(T: typedesc)= echo T.type
  a(float)
  a((int, int))

Current Output

float
stack trace: (most recent call last)
/usercode/in.nim(4, 6)   in
/usercode/in.nim(4, 6) Error: attempt to access a nil address

Expected Output

float
(int, int)

I have a fix for this one

[beef331]

With the fix I now have the same issue with the following. Starting to think might be wise to just avoid anonymous tuples for Nimscripter. 😄

static:
  proc test[T](t: typedesc[T]): T =
    discard
  echo test((int, int))
