include std/prelude vs import std/prelude (and other small prelude oddities)

[exelotl]

The disadvantage of `import`/`export` is that you lose the module names.

For example you could do:
    
    
    include std/prelude
    
    echo times.fromUnix(0)
    
    
    Run

But if it changed to `import common` you'd have to write this instead:
    
    
    import std/common
    
    echo common.fromUnix(0)
    
    
    Run

Admittedly this wouldn't be much of a problem for the stdlib where qualifying 
with the module name is almost never used, but it's why I use include for my 
own project's "prelude".
