It's been discussed recently, but I can't find it now. It's a 
natural result of the scope hierarchy: parameters are in a higher 
scope than the function body, into which the identifiers from 
std.stdio get imported.

It's been recognized that this is often unexpected, and different 
lookup rules have been debated, but I think there was no clear 
conclusion.

But in this particular case, it has already been fixed, and will 
work in the next release:
