• DESIGN CHOICES *

I've chosen to stick with many of the core ParselTongue features excluding Objects and its GetField/SetField types.

I have added the following core types:

• CByte: maps to Racket strings (this will mean the interpreter will need to ensure the string passed to CByte represent the ASCII value of single bytes)
• CByteArray: same as CByte except it is mutable
• CList: maps to Racket vectors since Python lists are mutable
• CTuple: maps to Racket lists since Python tuples are immutable
• CRange: maps to Racket lists (the desugarer will need to generate the appropriate numbers based on the arguments passed to the method)
• CDict: maps to Racket hash tables
• CSet: maps to Racket vectors since Python sets are mutable
• CFrozSet: maps to Racket lists since Python frozen sets are immutable
• CClass: this will desugar to a function and therefore it's similar to a closure

So, the values that can be returned are as follows:

• VNum

• VStr

• VByte

• VByteArray

• VTrue

• VFalse

• VNone

• VException

• VList

• VTuple

• VRange

• VDict

• VSet

• VFrozSet

• VClass

• VClosure

• CODE STRUCTURE *

The code structure hasn't altered from what was originally given to us on GitHub. The desugarer and interpreter follow the same style as what we did for ParselTongue.
