Try this FAR simplier case, which does work.
my %hash = (
key1 => "value1",
key2 => "value2"
);
print join (" ", @hash{qw<key1 key2>});
Appears the array symbol is required, and probably the above would need to
be changed to:
print join (" : ", @{%$_}->{qw<dir tpl ext rgx>}) . "\n" for @$cfgs;
but that's guessing. I hereby leave making it work correctly as an exercise for the
reader.
