Yes and No. No, what they are talking about is a parallelizing compiler.  
i.e. one that performs automatic parallelization / code analysis, which  
for the most part doesn't work because it has no grantees. And yes, pure  
is all about giving the complier the grantees it needs to actually  
automatically parallelize the code.
