Ranked in these QuestionsQuestion Ranking
Pros
Pro Python interop
Hy compiles to Python's abstract syntax trees. Python can import Hy modules, and Hy can import Python modules.
Pro Easier to read
Distinguished between arrays (or vectors) and function calls by using [] and (), respectively.
Pro Copyfree and open source
Uses the MIT (expat) license.
Pro IDE support
The open-source #develop comes with Boo support.
Pro Static type safety
This also improves performance as compared to IronPython. You can still use duck typing if you want, but you mostly don't need to since Boo can infer the type based on context.
Pro Inter-operates with other .NET languages
Boo runs on the .NET platform, so you can pretty much use it for anything C# is good for.
Pro One of Unity's supported languages
Use your Python skills to make games.
Pro Familiar syntax
Boo's syntax was heavily influenced by Python's, but makes some improvements like macros and multi-line lambdas.
Cons
Con The documentation isn't as good as Python's
There are some Boo textbooks. You can also find examples of Boo's language features in the Git repository, but it doesn't seem to have a thorough description of the language itself like Python does.
