|HeartForth An Emoji Based Language|

This was thought up for Valentine's day but it isn't too late for next year! It also has some interesting technical side issues that make stack-oriented languages look attractive.
This is a simple idea. Take the stack-oriented language Forth and replace each of its commands by an emoji. As it was Valentine's day, Neil Kandalgaonkar picked gooey squishy hearts and similar emoji, but in principle you could pick any theme you care to.
So, for example, the program:
You get the idea from just one example.
The claimed "advantages" are:
Stack-based languages like Forth are ideal for this sort of symbol swap because they have a simple syntax - nothing but operators and operands. So you don't have to invent complicated pairings of symbols as in if...then...else you can simply map operators to emoji.
It also makes the problem of tokenization, usually the first stage in any language, trivial - no matching of strings to pick up keywords like dup, or swap or... You just scan for the Unicode. It is a bit like the old Sinclair Spectrum keyboard with each key producing a token byte for the keyword in question.
So does it have any real use?
Probably not, but Forth, or any stack-oriented language, is something that is worth learning about.
If you do make use of this open source project next Valentines day, I have one small piece of advice. Try to avoid the dump operator!
Not only is it inefficient, it probably sends the wrong message!
