For all quoting constructs that use user-selected brackets, multiple,
-adjacent, identical opening brackets must always be matched by
-an equal number of adjacent closing brackets. Use of two or more
-brackets disables bracket counting within the quoted text and merely
-scans for the closing set of brackets. Hence this comment legally
-contains unmatched brackets and even an unmatched C<{{>:
-
- #{{
- Comment contains unmatched { and { { { { and {{ and } and } } but not:
- }}
+adjacent, identical opening brackets must always be matched by an
+equal number of adjacent closing brackets. Bracket counting naturally
+applies only to sets of brackets of the same length:
+
+ say #{{
+ Comment contains unmatched } and { { { { plus a counted {{ ... }} pair.
+ }} q<< <<woot>> >> # says "<<woot>>"
Note however that bare circumfix or postcircumfix C<<< <<...>> >>> is
not a user-selected bracket, but the ASCII variant of the C<< «...» >>
