re.findall finds all non-overlapping matches, but what if one wants
all (maximal) matches, even those that overlap?

All the solutions I can come up involve calling re.search iteratively,
each time giving it a pos parameter starting just after the start
of the previous match.

Is there a built-in solution to such a task?

TIA!

Not in the re module.

It has been requested and is in my regex implementation at
http://bugs.python.org/issue2636 if you want to try that.
