In Perl 6 you make lazy scalars by putting curlies around them:
my( $s, $t ); $s = { "value t is $t" }; $t = "xyz"; print $s();
Currently we also require the de-lazifying context to supply a
postfix .() marker, but possibly that could be assumed in a string
or numeric context.
I really don't see much benefit in making it easier than that.
