Hey Ludo,

I see, thanks for explaining.

> Why not just replace ‘par-map’ with ‘map’?  That sounds easier and I
> suspect it doesn’t change much performance-wise.

The objective was to still be able to run parallel input fetching, but
you're right, a simple "map" is nicer.

> (There’s a 2nd use of ‘par-map’ in that file.)

Oh! Fixed too.

Thanks for the quick answer,

Mathieu
