Whilst async truth test

[gobwas]

Why in whilst method (and brothers) truth test designed sycnchronously? For me its very often reason to write my own whilst, with async test. May be we can add it? If yes, i can implement it.

Sorry, if Im wrong.

Yes, it's designed to be synchronous. Maybe work the test into the iterator part?

Yes, it is possible, but not looks as clear design, isnt it? Its one unnecessary closure. ) Anyway it is interesting for me, which reasons was to design test this way? =)
