That's a variable-interpolated, brace-balanced string, just like a double
quote.  So it's like "foo $bar stuff" except your braces can nest (and you
may use any sort of brace: curly, square, round, or angle).  There's also
a form for non-variable interpolated strings, q{}, which is like a 'single
quote', as well as qx{} for `back quotes`.  Finally, qw{} is just a
listified q{}.
