The character `|` might work too. It looks better if we close it 
with the same character.
```d
    x = |std.datetime|SysTime;
```
I actually like this one a lot. There is some potential lexical 
ambiguity with `|` and `||` as binary operators. However, those 
operators are typically separated with whitespace in ordinary 
code, so I don't think it will ever be a problem. (The second `|` 
in `|std.datetime|SysTime` can be parsed as a part of 
`|modname|symbol`, so apart from typos, there's no syntactical 
problem.)

The worst you would suffer would be the visual confusion of 
something like this:
```d
if (|std.something|condition(sdfd) || 
|some.other.inlinemodule|Test
       || |othermod.imp|mycondition) {
    myFlags = |std.something|Flagset | |std.otherthing|Flags;
}
```
This would be the extreme case I think. Syntax highlighting could 
help.

I think this is better than `$std.datetime:SysTime`.
