5967 :: func/proc blocks

  If we can say

  type
    Xtype = object
    Ytype = object
  Run

  instead of

  type Xtype = object
  type Ytype = object
  Run

  then shouldn't we be allowed to say

  func
    f() =
      42
    g() =
      99
  Run

  There are probably more examples where blocks could/should be allowed.

  I like this. I also think that it could reduce the amount of forward declarations needed by allowing procs in the same proc section to be mutually recursive. This is already the case with type sections, so why not procs too?

  Because you don't have

  import
    module1
    module2
  Run

  ?

  But you can have func inside func.

  But we do have,

  
  import module1, module2
  Run

  I considered this in the beginning of Nim, but decided against it for multiple reasons:

  • Yet more ways to write the same.
  • The proc AST for macros would be slightly harder to work with.
  • Procs usually have more lines of code than type descriptions, "proc sections" don't look good anymore for realistic examples.

  imports can be an indented block.

  when grep-ing I find it quite useful to always have proc/func/template/macro before the proc name so I can easily distinguish between definitions and call sites.

  And what Araq said about the AST. Working with type sections or const/let/var I always opt to create a separate one when generating code because it's easier. And for parsing it would require supporting the 2 kinds of definitions.
