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")

Ooops.. i forgot some { } in the *UN*tested code... see if you can spot
where

4. Re: wish list : functions within funcions
When I understand the problem well, the anser is quite simple.
Just put the function you wat to use a level higher (In front of the first
function in which you want to use the common function) and everything goes
fine.
5. Re: wish list : functions within funcions
what i meant was that it would be nice if you could use *local* functions,
just like variables are local to function/procedure. the main reason for
this wish is that the name of function could then be simple, and it would be
also clearer.
In C you can use macros (with #define) and then undefine them at the end of
the function (at least thats what i did)
