Default allocator of container plus element type

[Nordlöw]

Would it be possible to set up a mapping (either formal or 
informal) of each typical container (such as array, linked-list 
etc) plus element type to a suitable default allocator? And 
perhaps add this to the documentation of 
`std.experimental.allocator`?

I currently get the feeling that most programmers have no idea at 
all what allocator to choose for each given combination of 
container and element type they want to use.
