cast

cast & coerce values

todo

• curry(2, coerce(type, arg))
• add serialize for persisting & hydrating with strings, using new Function as needed (mark in metadata)

why?

TypeGuards

(the assumption based on research & testing the compiled code, though it is likely there are more things to check and more known unknowns)

• megamorphic code wrapping the monomorphic code is perfect
• with the arg casting, it makes a solid decision tree, which ends up just becoming a GO TO LINE# -> easily optimized cast function "
• this is how typescript should compile
• this is likely why lodash has internal functions called base
• the other way to handle it is throw errors with invalid types
