This goto request reminds me of some of BASIC's kludges.
INPUT A
on A goto 1, 2, 55, 312

I despise jumping around a program in such a disorderly fashion.
(IMO): if this were to be implemented into Euphoria, it would
greatly degrade the simplicity that everything is linear or
calling a function/procedure.  With GOTO, your second line of
code can be abort(0) yet still have a fully functioning program.
YUK.

Try this on for size.

GOTO Start
abort(0)--never used.

Start:
puts(1, "The above was easily bypassed and is useless.")

GOTO's are one of the strongest components of spaghetti code.
Without goto, creating spachetti code is more difficult.
