perl6 --version
This is Rakudo version 2016.07.1 built on MoarVM version 2016.07
implementing Perl 6.c.

A postcircumfix operator that uses '>' as its closing delimiter is not
correctly recognized. For example​:

  sub postcircumfix​:« ¦ > » ($p, $v) {
  return $v => $p;
  }

  say 0.5¦'alive'>;

produces​:

  Missing required term after infix
  at /Users/damian/tmp/temporary_file.p6​:8
  ------> say 0.5¦'alive'>⏏;
  expecting any of​:
  prefix
  term

The same behaviour is observed when any other character that can be an
infix operator is
used as a closing delimiter.
