I suspect you previously used the other way: coding before thinking.
AFAIK this is Copyright (c) 19xx-2000 Microsoft Corp. Did you pay for
the right to use it? ;-)

That depends.

Flex does it this way
^\(ab\(c*\)def\)|\(hi\(j*\)\)\)

i.e. at the beginning of the line either ab with multiple c's and def
following, or hi with multiple j's.

Thy word's in God's ear. :-)

Sounds great,
