Re^7: Unescaped left brace in regex is passed through in regex

> So, I think "aha, it's a hex representation", but then I can't get there with the REPL:

you are still confusing interpolation (double-quotes) from literal strings (single-quotes)

  DB<28> p $str1 = "\x{41}"         # interpolation
A

  DB<29> p $str2 = '\x{41}'         # literal
\x{41}

  DB<30> p $str2 = '\\x{41}'        # literal but escaping escaping \
\x{41}

now, the double escape in line 30 is playing safe, because there is a difference between \\' and \'

BUT this

\x{ 263A }          Same, but shows optional blanks inside and
                    adjoining the braces

doesn't work for me! (oO ???)

  DB<31> p " \x{ 41 } "
