Further to that, I noticed that the somewhat arcane semantics of p5 split
are not honoured by Pugs. Since S29 split is not written yet I'm not sure,
but I expect p6 split will be p5 split compatible. For example, p5 split
retains leading empty fields, but lops trailing ones:
# cat s.pl
my $x = ":a:z:";
my @x = split(":", $x);
for (@x) { print "v='$_'\n" }
# perl -w s.pl
v=''
v='a'
v='z'
# pugs s.pl
v=''
v='a'
v='z'
v=''
The sometimes seemingly arbitrary semantics of p5 split seem to have become
something of a de facto standard, with even Java and .NET following suit
(I *think*, not certain about this and too lazy to check right now).
