Subject: [PATCH] fix parsing of braced subscript after parens
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Where an arrow is omitted between subscripts, if a parenthesised
subscript is followed by a braced one, PL_expect was getting set to
XBLOCK due to code intended for "foreach (...) {...}". This broke
bareword autoquotation, and the parsing of operators following the
braced subscript. Alter PL_expect from XBLOCK to XOPERATOR following
a parenthesised subscript. Fixes [perl #8045].
Petr Písař: Ported to 5.26.1.
