++ for being more idiomatic than I. Good follow-up. I must cantankerously contend that since I don't believe perl should parse this way, though, I will still refuse to code with that usage.

Tangent:

You see, it's too obscure, IMHO. In some contexts, people have thought that merely having parenthesis made a list context, when in fact it is comma operators that are doing so (as per a famous rant by mjd that I have no reference to at this moment); so in my book this idiom is truly obfuscated. Yes, it is handy to have a way to say my ($scalar)= to force a list context, but as syntactic sugar it tastes remarkably sour to my buds. It's a dank dark corner of perl that I want to stay away from.

Still, very ++ for explaining to me. At least I may remember what I am looking at next time I see it, even if I choose not to use it.

Sure.

my $binary = file_name_is_absolute($^X)
    ? $^X
    : (
        grep -x,
        map catfile($_,$^X),
        split /\Q$Config::Config{path_sep}/, $ENV{PATH}
    )[0];
