Hi over there,
this has been discussed years ago in mathgroup, I believe, and one of the more awkward suggestions was M.A.P.L.E. (Ma
) - to my regret I cannot find a reference anymore - after that proposal the issue faded out. So, more seriously, the Mathematica Reference speaks about "Mathematica Core Language", this would be "MaCoLa", or, in the extreme: "CoLa".
By the way, there is Coca Cola and Pepsi Cola, if you could place another <X> Cola, it would be a buster.
Wolfram Programming Language is WoProLa (sounds like an eastern german synthetic fibre) - not appealing, WOPLA - you wan't read this again, Wolfrapl - yeah!
Let's turn back to the question, what is the <X> in <X> Cola? What does Mathematica: It lives from Stephens insight into the structure of expressions, therefore doing far more than algebra, analysis or other mathematical stuff. It's a type of framework to get things in an out of a computing facility (and transforming it inside - of course).
In German there is the term "Stellenalgebra", a "Stelle" is the # in Lambda-Expressions, therefore I would propose the name Lambda Cola
Think about it, it consists of 2 words, each word has 2 syllables and as "Lambda Core Language" it's not too bad a description about the intentions and workings of Mathematica.
P.S.: (... there is the MOMA in New York and the MOMATH is in New York too ...)
