Hi,
as any one encounter this type of class def and can explain the pattern

Class A cosntructor(...) : (String) -> B {

}

[Ruckus]

it's a class that implements the (String) -> B interface (you can think of it like Function<String, B> from Java).

[AnnoymousGiraf]

What would be a good use case for that? or a pattern ?

[Ruckus]

That's difficult to answer. Basically when you want a function type that has state. Whether that makes much sense is up for debate, but could possibly be necessary to work around libraries/APIs that don't envision your use case.

Cheers will have a look into it

[AnnoymousGiraf]

OK, i looked on the Function interface it is indeed in order to force apply impel. probably sort of Command Pattern

Function1<String, B> maybe :)
