Perl always allows curlies to surround the symbol's name (or expression) following sigils!

So

$txt =~ s/test/${foo}bar/;

instead of

$txt =~ s/test/$foobar/;

Documentation wasn't easy to find:

As in some shells, you can enclose the variable name in braces to disambiguate it from following alphanumerics (and underscores). You must also do this when interpolating a variable into a string to separate the variable name from a following double-colon or an apostrophe, since these would be otherwise treated as a package separator:
