I forgot to post it, but it doesn't matter, let-closures are not not native-compiled, gotcha. >>>> Maybe function that are made up of functions that have >>>> their types inferred also get their types inferred ... >>> >>> Of course they are typed as well, but we can use the types >>> of the called functions for propagations as they can be >>> redefined in every moment. >> >> We can? > > Apologies for the typo, wanted to write _can't_. Are they used for propagations at native-compile time? Because how else is the function type inferred? And is it true that the type inferred for a particular function is only guaranteed to hold at native-compile time, if that is when it happens? Because if we have f(x) = a(b(c(x))) and a, b, and c can be redefined at run time, how can we know the type of f at run time? Without again do native-compile of c, b, a, and f that is? Are there functions to do inference so I can try them on random functions? BTW I like it how the type is expressed in Lisp B) -- underground experts united https://dataswamp.org/~incal
