:Um, OK, except my example used a quoted brace-bracketed string with variable
:interpolation deferred until a later point. Can you do deferred variable
:interpolation in Perl?
Sure; just use q{no interp on $var for now}, and then interpolate it later,
probably with things like
$string = q{no interp on $var for now};
.....
$newstring = eval qq{"$string"};
Umm - won't this do?
$string = sub { "no interp on $var for now " }
....
$newstring = &$string;
