Attempting to free an active format or the handle associated with it no
longer results in a crash.

+Format parsing no longer gets confused by braces, semicolons and
+low-precedence operators. It used to be possible to use braces as format
+delimiters (instead of C<=> and C<.>), but only sometimes. Semicolons and
+low-precedence operators in format argument lines no longer confuse the
+parser into ignoring the line's return value. In format argument lines,
+braces can now be used for anonymous hashes, instead of being treated
+always as C<do> blocks.

+
+Formats can now be nested inside code blocks in regular expressions and
+other quoted constructs (C</(?{...})/> and C<qq/${...}/>) [perl #114040].
