Yeah, and Python competes against Ruby against Perl against Javascript against Python 3 against Perl 6. Without sharing any code. And you win almost nothing. CPython, Perl, Ruby, ... are all slow scripting languages. With the newest implementation, Ruby, being the slowest programming language of all.
CL implementations can share a lot of code.
I've just compiled Mark Tarver's Shen in another Lisp by just changing less than ten lines of code. It took me ten minutes.
