Improve the handling of builtins #27

Closed skx closed 6 years ago

skx commented 6 years ago

This will allow us to handle recursive calls to built-ins in the future, so for example:

10 LET a = RND RND 100

The first RND will take the result of the second RND as argument. Similarly we can use this in goserver:

10 COLOR RND 255, RND 255, RND 255.

Almost there :)

Next obvious thing to change is that the builtin-functions return:

object.Object, error

Since object.Object can now return an error (as result of #22) the second parameter is redundant. Drop it.

Fix the tests tomorrow, then it's a go I think.
