This works for me: 
perl -we "use strict; sub subby(&\@\@){print qq|in subby..@{$_[2]};\n|
+}; my @x=subby sub{print qq|calling...|},my @c, @{[ grep {/\d/} 0..6]
+}"

OUTPUT:
in subby..0 1 2 3 4 5 6;

Basically - encapsulate the "grep" result into something that looks like an array (Make an arrayref and dereference it).

But, like Fletch said .. do the right thing, and declare it properly.
