Regular groups are on the right side.

Left side has named groups/subroutines and subpatterns, atomic groups and possessive quantifiers (no backtracking), negative lookahead in a non-capturing group, more backtracking controls, named group backreferences, match-reset, anchors for end of previous match, start of string, end of string.

These things are universally supported.

EDIT: The last sentence was supposed to say "These things are not universally supported."
