How come toLower works in the sort quotes, but not in the map?

.map!(c => c.toLower)

When you pass a string to a lambda, it's evaluated in
`std.functional.unaryFun`/`binaryFun`.
At that point, these modules are imported for use in string
expressions:
```
import std.algorithm, std.conv, std.exception, std.math,
std.range, std.string;
import std.meta, std.traits, std.typecons;
```
And `std.string` itself publically imports:
```
public import std.uni : icmp, toLower, toLowerInPlace, toUpper,
toUpperInPlace;
```
But does *not* import `std.ascii`! So there's no ambiguity inside
the `sort` string expression between the two `toLower` functions..
