[REBOL] Re: Linguistic influences
From: rotenca:telvia:it at: 12-May-2002 16:36
for me the best mode to do that in Rebol is to use a parse rule:
result: copy 
r: [into r | set x skip (insert tail result x)]
parse/all serie [some r]
It is the more simple and the more fast (i think).
But the point is that it also the more easy to understand, if one has a
sufficient knowledge of the innatural Rebol parse rules which are distant, i
think, from any natural languages rules.
So i ask myself what is "naturality".

I asked for a /tail refinement in insert. It should be also possible to create
alias of refined words.

About Change, I feel the need of a change/part which changes only a fixed
length of the destination series with a fixed length of the source series.Now
the /part refinement works like insert if the length of the source series is >
than the /part argument. Now we must do a copy/part on the source series to do
a true fixed lenght Change. If the source is very long, this is a real waste
of time and memory.
But i could not see a different mode to make it in the current version of
Rebol. Anyone see it?
