I have #Develop 2.0 and it gives me the option to program in a language called "Boo" anyone heard of it?

Yep. It's a .NET language with a language similar to Python. Some interesting features of note:

1. Comprehensions and generators, i.e.

(Toggle Plain Text)

children = [person for person in person if person.Age < 18]

2. Anonymous blocks (i.e. anonymous delegates or lambda expressions):

(Toggle Plain Text)

list = map({ x | x + 1 }, [1, 2, 3, 4])    # -> [2, 3, 4, 5]

3. Type inference:

(Toggle Plain Text)

list = (1, 2, 3, 4)     # list is automatically defined as int[]

4. User-defined macros that can alter the ASTs of their enclosed blocks:

(Toggle Plain Text)

addfootoallstrings:
    print "hello"    # prints "foohello"

Boo is nice, but it's a little rough around the edges at times, and has some syntactical curiosities where you think something should parse, but doesn't. That said, it's still only at version 0.7.x, and the parser itself is very well written and easy to extend.
