I agree with you, prefixing stuff with Static… adds exactly no value. 
The problem is that Phobos defines quite a few types of similar names 
for the return type of the »dynamic« higher order functions (or rather 
defined, Andrei has been migrating them to »opaque« auto retuns), which 
could lead to confusion.

My plan was to drop any prefixes, simply calling the templates Map, 
Filter, and so on, choosing the case depending on whether a 
template/type/type-tuple or value is returned, and encourage users to 
use renamed imports for clarity in cases where it's not obvious (i.e. 
import meta = std.meta).
