Perl's regexen are this way, and checking the man for a GNU
Repetition takes precedence over concatenation, which in
turn takes precedence over alternation. A whole subex-
pression may be enclosed in parentheses to override these
So `|' is the lowest precedence, '*' et al are the highest
precedence (bind more tightly).
