On 5.16.0 (at least), I get different results from yours:
#####
$ perl -MData::Dumper -E '$_ = "\x20a\x20b\x20c\x20";@r=split /\x20/;say
Dumper \@r;'
$VAR1 = [
'',
'a',
'b',
'c'
];
$ perl -MData::Dumper -E '$_ = " a b c ";@r=split /\x20/;say Dumper \@r;'
$VAR1 = [
'',
'a',
'b',
'c'
];
#####
Nonetheless, these results appear to fail to match the documentation in
a *different* way from yours, viz., they fail the specification that
"any leading whitespace in EXPR is removed before splitting occurs."
Thank you very much.
