Also, in my code the separate patterns are compiled much before the disjunction, so this is not what I’m looking for:

But that is what you get. You cannot combine the compiled forms of precompiled regexen, they must be stringified for concatenation and the result has to be recompiled. There’s no way around that.

So the last snippet is what you want. Sorry.

Btw, the stringified regexen supply their own (?:) delimitation, so all you need to do is

my $joined = do {
    local $_ = join '|', @any;
    qr/$_/;
};

Update: added do as per gaal’s reply.
