<wollmers> I wonder if the specs allow insignificant white-space in
literals, e.g like say "\x[ c4, 20, c4 ]";
<masak> std: say "\x[ c4, 20, c4 ]";
<p6eval> std 26365: OUTPUT«ok 00:04 35m␤»
<masak> rakudo: say "\x[ c4, 20, c4 ]";
<p6eval> rakudo 5c8015: OUTPUT«perl6regex parse error: Invalid digit
in \x[...], \o[...], or \c[...] at offset 19, found ' ' [...]
<masak> wollmers: opinions differ. :)
