here a partial solution using glob

But I don't know how to escape the "," appropriately ...°

use v5.12;
use warnings;
use Data::Dump qw/pp dd/;


my $globber = join ",", (":", ";", "=", "-");

for my $line (<DATA>) {
    chomp $line;
    say "--- $line";
    $line =~ s/\s/{$globber}/g;
    say pp [ glob($line) ];
}

__DATA__
/a/b/c/d/e/fi le
/a/b/c/d/e/fi l e
/a/b/c/d/e/f i l e
/a/b/c/d/e/f i  l e

output
<Reveal this spoiler or all in this thread>

°) one workaround may be to use a placeholder like "\0" which can't naturally appear and to replace it afterwards.

update

the whole concept is dubious, because this will create far too many combinations. (Besides solving the original issue) it's better to check incrementally from left to right with wildcards, before progressing to the next position.

my @part = </a/b/c/d/e/f{;,:,=,-}i*>;

etc
