Summary
Okay Joy has more than two problems, but two problems really stick out.

Achilleas Margaritas and I are designing a concatenative programming language as an alternative to Joy called Unimperative. So far we have identified two major problems with Joy, which we are seeking to address:

1. The syntax is backwards. e.g. (5, 2, add, 3, multiply). Well at least from a Westerner's perspective. My apologies to my Arabic friends who may disagree. Unimperative will be flipping the syntax back around to the more common prefix notation (multiply, 3, add, 2, 5)
2. There is no type checking. Type checking can be very useful for debugging and understanding code. It's kind of silly to be obliged to check documentation to see what a function expects to see on the stack. Currently we are discussing the precise syntax to use. I am trying to get Achilleas to agree on the following :

   let<List> second = (first, rest); 
   let<int> double = (multiply, 2);
