added args() function

[sysread]

Adds a new abs function, args(), that returns the number of arguments to the current script, including
the script itself. This is useful for scripts which accept a variable number of positional arguments (for example, a list of files).

Amazing! Would you mind adding a test for the function?

[sysread]

I'd be happy to. Do you mean a go test (I wasn't certain where those would go - evaluator/evaluator_test.go?) or a abs test in tests?

[odino]

In the evaluator package :) You can see similar tests here! cheers!

[sysread]

I've added the test and rebased the branch in my fork.

I've been thinking about the semantics of the args function a bit and I believe it might be better to have it return a list of arguments. When you call args() you'd probably expect the arguments, not their length, back. One can still figure out what is the length with args().len(). What do you think?

[sysread]

Updated.

[odino]

Nice!

This is about to be released. I've made an exception and included it as 1.8.3 though next time we add a feature it should go in the next minor release (1.9.x at this point in time). Regardless, thanks a bunch!

[odino]

It's released, have fun 😄
