Sure, though in any case I'd probably prefer:

    $ perl6 -e 'my $foo = "foo"; say Qs/{$foo}/'

Not unless something outside of it all was attempting to count braces.
But the P6 parser has sworn off all such activities for P6-derived
code.  Parsing something first as a string and then again as some
other language is generally looked upon as a Bad Plan these days.

Which is, of course, why "{" is a problem now.  Perhaps use of nested
double quotes deserves a warning.
