cperl-next-interpolated-REx is an interactive compiled Lisp function in `
(cperl-next-interpolated-REx &optional SKIP BEG LIMIT)
Move point to next REx which has interpolated parts.
SKIP is a list of possible types to skip, BEG and LIMIT are the starting
point and the limit of search (default to point and end of buffer).
SKIP may be a number, then it behaves as list of numbers up to SKIP; this
semantic may be used as a numeric argument.
Types are 0 for / $rex /o (interpolated once), 1 for /$rex/ (if $rex is
a result of qr//, this is not a performance hit), t for the rest.
