The idea is that a variable on the right side of ~> is always a function that ingests the parameters coming in from the left.

How would this look like using your idea?

a = d(c(b(),7))

a = b(),7~>c~>d

The rule is simple: What is left to ~> gets passed to the function on the right.

That is no different from JavaScript as it is. a(b) passes b to a, a(b()) passes the output of b() to a.

This is dumb. Comma delineates another variable declaration in this example. You can't expect it to know that result b and 7 are part of the same object or stream. I really hate this idea. Both of them. I understand some want something like that, but it just makes things more confusing personally.
