This is a bug report for perl from zoffix@zoffix.com,
generated with the help of perlbug 1.39 running under perl 5.18.1.


-----------------------------------------------------------------
[Please describe your issue here]

The fat comma operator (=>) doesn't seem to quote v-strings when used in
the "use BLAH v1 => 42" lines. A particular example is "use constant v1
=> 42" The v1 should be quoted by the => operator, but that line of code
produces a syntax error:   "syntax error at -e line 1, near "use
constant v1 =>""


[Please do not change anything below this line]
