As a reasonably fluent Forth programmer, I find the comparisons to Forth a source of confusion, at best. In Forth a compiled word definition begins with : and ends in ; while Play definitions begin at :def, use : to separate signatures from word bodies, and appear to be implicitly terminated wherever the next definition begins. Forth definitions always appear in "reading order"- words are declared before they are used- but the very first example on the Play home page inverts this convention. It feels rather like reading pig-latin, or perhaps ML wearing a Forth-skin-suit. Forth's hybrid compiled/interpreted nature is at the heart of its expressiveness; so far as I can tell, this is entirely absent from Play. How would I define a word like "when:", "def:", or "["? In my opinion it would be clearer and more accurate to describe Play as simply a concatenative functional language.
