DEFER #11

Open larsbrinkhoff opened 7 years ago

larsbrinkhoff commented 7 years ago

Add DEFER, IS, ACTION-OF, DEFER@, and DEFER!.

A deferred word should probably compile to a single jump instruction.

IS should work at both compile time and run time.

On second thought, that wouldn't work on machines with read-only or inaccessible program memory.

The problem is similar to VARIABLE : another level of indirection is required. And, of course, initialization.
