Example:
U.lift((value = 'bar') => console.log(value) || value)(Kefir.constant('foo'))
Lifted function logs observable instead of the unboxed value. From quick glance of the source code, I think the cause is checking function.length
inside lift function, it seems to only count the parameters which are before the first parameter with default arguments.
Not sure if anything can be done about this though, but it was a cause for funny bug in our code.
Maybe a warning if arguments.length and fn.length don't match?
Example of unexpected behavior:
var o = {}
K(o, o_ => console.log(o === o_)) //true
K(o, 'test', o_ => console.log(o === o_)) //true
K(Kefir.constant(o), o_ => console.log(o === o_)).onValue(() => {}) //true
K(Kefir.constant(o), Kefir.constant('test'), o_ => console.log(o === o_)).onValue(() => {}) //true
K(o, Kefir.constant('test'), o_ => console.log(o === o_)).onValue(() => {}) //false
