[issue31580] Defer compiling regular expressions

[Ezio Melotti]

Ezio Melotti added the comment:

What about adding a lazy_compile() function?  It will leave the current behavior unchanged, it's explicit, and it's easier to use cross version (if importing re.lazy_compile fails, use re.compile).

FWIW I'm -1 on changing re.compile, -1 on adding re.IMMEDIATE, -0.5 on adding re.DEFERRED (not sure this option belongs among the re flag), +1 on adding a compile-time optimization.
