This is a bug report for perl from l.mai@web.de,
generated with the help of perlbug 1.40 running under perl 5.20.1.

[Please describe your issue here]

$ perl -we '[]'
Useless use of anonymous list ([]) in void context at -e line 1.

I don't like the "anonymous list" bit. [] constructs a reference to an
anonymous array. [] is a circumfix operator *surrounding* a list, but the thing
in void context is not a list (besides, how can you have a list in a non-list
context?).

I think this op should be renamed to "anonymous array".
