LPython seems more like Shedskin. (Shedskin compiles Python to C++.)
You could say that LPython and Shedskin are to Python what Crystal is to Ruby.
imo that misrepresents crystal, which is not a compiler from ruby to c++/native but a separate language that takes a lot of inspiration from ruby and tries to maintain a similar syntax, but does not consider itself a ruby dialect or implementation.
I think you are right, it wasn't a great comparison.
