An alternative to no strict 'refs' would be:

foreach my $pkg ( @pkgs ) {
   my $hello = "Test::$pkg"->can('hello');
   $hello->() if $hello;
}

... because can returns a coderef. In the case of packages that have inheritance (@ISA) this will act slightly differently to &{'Test::' . $pkg . '::hello'}().

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
