Message-Id: <5.8.7_3884_1145571853[at]frederick>
This is a bug report for perl from jeremyhetzler[at]gmail.com,
generated with the help of perlbug 1.35 running under perl v5.8.7.
-----------------------------------------------------------------
The error message when passing exists() a wrong argument type is:
$ perl -e'exists $foo'
exists argument is not a HASH or ARRAY element at -e line 1.
Likewise, /bin/splain reports:
$ perl -e'exists $foo' 2>&1 | splain
exists argument is not a HASH or ARRAY element at -e line 1 (#1)
(F) The argument to exists() must be a hash or array element, such as:
$foo{$bar}
$ref->{"susie"}[12]
However, the argument to exists can legitimately also be a subroutine
name:
$ perl -e'exists &foo'
The docs correctly state that the argument can be any of a hash element,
an array element, or a subroutine name.
The error message should be:
exists argument is not a HASH or ARRAY element or subroutine name at
-e line 1.
The splain output should be:
(F) The argument to exists() must be a hash or array element or
a subroutine name, such as:
$foo{$bar}
$ref->{"susie"}[12]
&foo
[Please do not change anything below this line]
