Sometimes "explain" is missing from Error::TypeTiny::Assertion

This code:

#!/usr/bin/perl -w
use strict;
use Type::Params qw(compile);
use Types::Standard qw(Dict Int);

for my $sub (
    sub {
        my $check = compile(Dict[key => Int]);
        $check->({ key => 'f' });
    },
    sub {
        compile(Dict[key => Int])->({ key => 'f' });
    },
    sub {
        my $check = compile(Dict[key => Int]);
        $check->({ key => 'f' });
    },
) {
    print "\n", "#" x 80, "\n";
    eval { $sub->() };
    print $@;
}

Produces this output:

I would have expected all these tree subs to produce the same $@ - but they don't. In addition, the first sub (without the explanation) is missing a newline. That has been fixed in pull-request #33.
