I have been following the goto debate with interest. I believe that
the carefull use of goto is very useful for simplifying code and
I intend to add it to the Euphoria source.

I originally decided against it because it
seemed very difficult, but after porting to LCC, adding
initializations, slicing shorthands, and references, it now
seems quite straightforward (should be about 2 days work). Using a
translator to change goto's into structured code would be WAY beyond
my capabilities.

A sample of the syntax I will be using is:

procedure foo()
   ...
   if ... then
      ...
      goto done
   end if
   ...
:done:
end procedure

Surrounding the labels with ':'s helps them stand out.

Labels and goto's will only be allowed in procedures or
functions.

Dangling goto's and unreferenced labels will be illegal.

Forward and backward references will be ok.
