Can this use a better name than "y"? I'd previously renamed this to "basedir" for clarity.

Hi @ljharb I just basically left @jmm's code intact, but I can certainly change y to basedir instead.

However, note that y is really just a temporary variable and not intended to have any significant meaning, I'm guessing from @jmm's code, because at the end of the day, what you want is, parent and y just splits up the derivation of parent into two parts for clarity.

Anyway, let me know whether you still want y to be basedir and I will make the change.

At the time they made their PR, the variable was called "y" :-) please do change it.

var parent = opts.filename || y;

opts.paths = opts.paths || [];
