Subject: wish list : functions within funcions


>I really miss the ability of language to use functions within functions. If
you want to do one thing often within function, but that thing is specific
only for that function. Now you have to write new function, which has name
similar to parent function, but is used only within one function.

That's called function overloading, in Eu, this can be easy. Pass the
function a sequence, then parse the sequence within the function to see what
should be done to it:

*UN*tested code!!
function dothings(sequence data)
 if sequence(data[1]) then
   if
     ( data[1] =  "puts" ) then puts(data[2],data[3])
  elsif
    ( data[1] = "DoSomethingElse") then DoSomethingElseHere
  elsif
    ( data[1] = "DoSomethingElse#2") then DoSomethingElse#2Here
  end if
 else
  if (data[3] = "add") then return data[1] + data[2] end if
 end if
end function -- dothings

dothings("puts",1,"hello")
dothings(1,2,"add")
