Sorry but there isn't. RDS believes this is the best way to do it. I strongly
disagree with RDS on
that issue.

The RDS philosophy seems to be that good programming practice is to only refer
to things that have
already been "seen" by the one-pass interpreter. Thus you cannot refer to any
identifier that is
defined lower down in the file. So yes, the physical layout of indentifier
definitions in a source
code file has been deemed to be vitally significant by RDS.

This means that you as a programmer have to invent cunning ways to get around
this limitation in the
language (as implemented by RDS). Of course, RDS has also recognised that there
are legitimate
reasons for coders to do this, so Euphoria has been provided with routine_id(),
call_proc/func()
routines.

My suspicions are that it is now too hard for RDS to change the way the
interpreter works to allow
for forward referencing, so we are stuck with this limitation for now.

Whenever I get a spare 12-months, I'll write a new implementation of the
interpreter
