Hi!

I want to use the regexp fragment for parsing purposes, but even your
simplest demo program (p. 86 in mia90-08.pdf) does not work with BETA
4.1:

ORIGIN '~beta/basiclib/v1.6/betaenv';
INCLUDE '~beta/basiclib/v1.6/regexp';

-- program: descriptor --

(#
	t:^text;
	do
	'Hello world' -> t[];
	('\\<w.*\\>', '\\0 champion') -> t.regexp_replace;
	t[] -> putline; (* prints 'Hello world champion' *)
#)


This program just produces a "Hello world" and not "Hello world
champion".
The very very simple

ORIGIN '~beta/basiclib/v1.6/betaenv';
INCLUDE '~beta/basiclib/v1.6/regexp';

-- program: descriptor --

(#
	t:^text;
	do
	'Hello BETA!' -> t[];
	('BETA', 'Mjolner') -> t.regexp_replace;
	t[] -> putline; (* should print 'Hello Mjolner!' *)
#)

only gives me a "Hello BETA!" and not the string that should be there.

Is the regexp fragment working in some way?

Any quick help is appreciated.
