Not to the matching engine, but to the regexp compiler.

It would be reasonable easy to implement backward-compatibly:  if a
string's first character has a non-nil "punc-are-operators" property,
then all punctuation would be interpreted as regex operators *unless*
they are escaped.

Neither the property name nor the API are likely to be optimal, but it
would work.  You could also do it with some kind of variable.
