proc/func/method: syntax

[Araq]

Fwiw I sometimes think about this alternative syntax:
    
    
    while a != b do
      if x == y do
        echo "yes"
      else
        echo "no"
      mymacro a, b, c do
        echo "code block passed to macro"
      else
        echo "else block also passed to macro"
    
    
    Run

But don't worry, I won't change anything.
