(aa) can never happen insidea. The fact that the expression is repeated does not change its inner logic. However, in Perl-like engines, the aforementioned regex does not match anyalonger than one character, because those engines treat lookarounds specially, effectively running a sub-regex at ...
a quantified character is repeated as many times as it possible. The RegEx engine adds to the match as many characters as it can and then shortens that one by one in case the rest of the pattern doesn’t match. Its opposite will be called the lazy mode which match as few characters ...
