has anyone made a .e doing regular expression matching, substituting, and
translating, just like they're done by grep or sed (and thus perl)?

That, and more... I want all
?? (one-time matching) syntax: ?PATTERN?
m// (matching) syntax: m/PATTERN/gimosx
// (matching) syntax: /PATTERN/gimosx
q// (single/direct quoting, maybe unnecessary) syntax: q/STRING/
qq// (double/interpolated quoting, will substitute embedded vars etc)
syntax: qq/STRING/
qx// (backquoting: execute, and return stdout) syntax: qx/STRING/
qw// (list of words, can be simulated quite easily in Euphoria)
syntax: qw/STRING/
s/// (substitution) syntax: s/PATTERN/REPLACEMENT/egimosx
e.g. s/do/did/g used on "Can we undo what he does?"
will give you "Can we undid what he dides?"
tr/// (translation) syntax: tr/SEARCHLIST/REPLACEMENTLIST/cds
y/// (translation) syntax: y/SEARCHLIST/REPLACEMENTLIST/cds
tr/// = y///
m// = //

Isn't \euphoria\include\wildcard.e useful here.
Granted you'd have to tweak the code a little to get true grep/sed-like
regexes, but there's a firm basis there.
I believe that at the moment is acts like the Un*x command line regexps:
com*d*.com => command.com
commodor.com
etc.
