Not having alternation (|) in the regex syntax does
actually cause some problems --- I have to try each regex
in succession until one matches.  I don't know how Lua's
pattern support works internally, I suspect I may be
spending more time compiling regexes than actually doing
work, during imports.

Lua patterns aren't compiled; the pattern string itself is
iterated through.  (See the function "match" in lstrlib.c.)
