Drop ok, err, some (both kinds), none from language

Alan v0.2 doesn't really need these functions for the optional and fallible types. You can just Maybe(val) to be equivalent to some(val), Maybe{myType}(void) to be equivalent to none (a bit more awkward, type inference should eventually support Maybe(void) for none), Fallible(val) for ok(val) and Fallible{myType}(errorVal) for err(errorVal) (again, type inference may help here). And the Maybe and Fallible "functions" could be bound to ? and ! postfix operators to turn that into just val?, void? (assuming inference works as desired), val!, and errorVal! (again assuming inference works as desired) which is even shorter.

At the same time, many languages have a different meaning for some, as an array method for determining if any of the elements of the array passes the provided check function. Alan since v0.1 includes a has function that accepts a value directly and returns true if that value is present in the array. This is like a shorthand for a check function that performs an equality check on the value, so I decided to expand has to also accept check functions, which therefore made it equivalent to some in those languages.

Since this language is aimed at both crowds, completely eliminating these terms from the language may be initially confusing, but should hopefully be less confusing than having a known term with a different meaning.
