Mine does. Braced time is a string and other time is a sub. And even:

grep {time} @somearray;
[download]

Sorry, wrong example. (I'm intentionally leaving strict off here. Enabling it would spoil the fun.) Is your IDE smart enough to catch the difference?

#!/usr/bin/perl

my %example;
$example{foo} = say;

print $example{foo}, "\n";
[download]

->> 'say'

#!/usr/bin/perl

use 5.010;

my %example;
$example{foo} = say;

print $example{foo}, "\n";
[download]

->> '1'

Nope, it doesn't. It parses script with implicit strict and say in your example will be always a sub call.

And, i've asked about exact two situations when perl (as far as I know) always treats bareword as a string.
