Why? All it means when a function is pure is that it can't access any static 
or module-level variables which can ever be mutated over the course of the 
program. It has nothing to do with shared or synchronization. True, there are 
circumstances under which calls to a pure function can be optimized out (e.g. 
when all of its parameters are immutable or implicitly convertible to 
immutable), but there's nothing stopping you from creating pure functions 
which take or return shared variables, and those functions could be called 
just like any other function which takes or returns shared variables.
