Well, if languages based on VMs that compile to an intermediate 
representation first and then interpret bytecode are *bad* then that 
sends CPython out of the window too...

Of course both .NET and the JVM have kick-ass JIT compilers, so maybe it 
is having a JIT compiler that is bad? That makes CPython good but PyPy 
and Unladen Swallow bad (along with IronPython and Jython of course). Hmm...

The cross-platform story for .NET is not brilliant, with Mono constantly 
playing catch-up and only just switching away from a leaks-like-hell 
garbage collector. Other than that the "technical arguments" that have 
been presented against .NET in this thread are poor.

All the best,
