Invalid syntax accepted

[kiedtl]

If the first element in a list is a list, that list is recursively parsed while the rest of the elements in the original list is ignored.

(((word main [])) tsdflsdf)

Not sure why this behaviour was there in the first place (in what cases would a list as the first element in a list be valid?)

Fix should be to simply only allow a keyword as first element in list. I'll have to test that nothing else depends on allowing a list to be first element however.
