Function type alias and c codegen error

[vegansk]

This code:

import future

type
  Func0*[R] = () -> R
  # This definition fails too
  # Func0*[R] = proc(): R

# This definition leads to error
proc memoize*[T](f: Func0[T]): Func0[T] =
# And this is not
# proc memoize*[T](f: () -> T): () -> T =
  ## Create function's value cache (not thread safe yet)
  var hasValue = false
  var value: T
  result = proc(): T =
    if not hasValue:
      hasValue = true
      value = f()
    return value

when isMainModule:
  var x = 0
  let f = () => (
    inc x;
    x
  )
  let fm = f.memoize
  echo f()
  echo fm()
  echo f()
  echo fm()

fails to compile:

It seems, that it is already fixed in devel. Closing...
