Feature Request: Blip.all(regular expression)

Would function similarly to the simple text search already available with
Blip.all(search string), but would find regular expression matches instead.
Additional functionality/arguments could include searching plain text only
and/or determining which ElementTypes should be allowed to be in the match.

This would allow for simpler and safer (it would make it harder to
unknowingly delete Elements, if the above-mentioned plain text only
flag/argument was set) search and replace of matches within delimiters like
a lot of those LaTeX-to-image robots do (text within $$...$$ gets replaced
by an image).

Currently the only way to work around the above-mentioned safety issue is
to iterate through blip.serialize().getElements() and check if any of the
indexes are in the range of the delimiters.
