with has undocumented behaviour

[ajb-in]

This will not work as documented:

$f = static function ($x) { return $x + 1; };
with($f, partial_any('map', [1, 2, 3], …));

@ajb-in thank you, good point. Have a look at the commit, what do you think?

[lstrojny]

Alternative would be to deprecate with() entirely and introduce with_value() and with_func() or something.

[ajb-in]

with should behave like with_value, period. If the value is callable, calling it should be the job of with's second argument.
Instead of with_func($f, $g) you could have with($f, partial_any(compose($g, …))).
Of course that breaks BC, but it could be a thing for the next major. No strong opinion on how to handle the transition.

[ajb-in]

Of course I'm an idiot; 496f677 does just that. LGTM.

Fixed in 1.2.1
