Re: Re: /foo${re}bar/

Why not /foo{$re}bar/? Just that {} already is used for repetition, and a number would get interpolated?

Which usage came first in Perl-time?

er, no. `${foo}` has been the standard way to disambiguate variables for a long time now and was independent of regex. Mostly used for strings, aside from this as in: `print "${Foo}bar"` and similar, also used for references, so called "soft" refs in the form of `${"foo"}` and hard refs in the form of `$x=\$foo; ${$x}` Also works with the various other sigils, $%@.
