254 :: curious about the reason of procedural types instead lambdas

  Hi..I'm new with nimrod and although everything than I had seen looks great, is very disapointed than nimrod use procedural types instead clear lambdas, is a bit annoying declare a type everytime than I wanna use a lambdas...

  type

  TCallback = proc (x: int)

  proc forEach(callback: TCallback) =

  instead of proc forEach(callback: proc (x: int))

  simple, clear and you don't need to be jumping across the code for check the type from the procedure

  so I'm curious, what is the reason about this approach, is an "acquired taste" from araq :D ...or are there other motives...

  simple, clear

  Simple and clear for single time use, for multiple times?

  The header compatibility must always be checked, it's a bit harder with untyped procedural type

  instead of proc forEach(callback: proc (x: int))

  That works. You don't need to define a type.
