Topics: Functions are required to specify arity and Detection of invalid operands for "jump" instructions

This was another slow week, and it resulted in almost no newsworthy developments.

Functions are required to specify arity

To disambiguate function names from labels, function names are now required to include an arity specifier at the end. The arity may be undefined for functions which require it. 

.function: example/0    -- a function with specified arity of 0 (a nullary function)

.function: example/1    -- a function with specified arity of 1 (an unary function)

.function: example/     -- a function with undefined arity

Detection of invalid operands for "jump" instructions

Invalid operands for are now reported for jump instructions. 

jump +1     -- OK, forward jump

jump -1     -- OK, backward jump

jump here   -- OK, jump to a marker

jump "Hello"    -- jumps to strings (or ints, or bits, etc.) are not allowed
