Is your feature request related to a problem? Please describe.
I want to using applicative in expression, like this example

Describe the solution you'd like

a = Some(5)
b = lambda x: Some(x)
a.apply(b)

thanks!

You can use a method bind.

import expression as ex

a = ex.Some(5)
b = lambda x: ex.Some(x)
a.bind(b)

Thanks for your reply!
I think bind is a flatmap and it's diffenrent from applicative,
if there are any applicative just like fp-ts apply?

You can also use the member function called map2
>>> Some(8).map2(lambda x,y: x+y, Some(6))
Some 14
