To elaborate more, `toLower` doesn't work because function-scope 
aliases are not considered for UFCS.

```
     alias toLower = std.ascii.toLower;

     ...
     // So this does actually work:
         .map!toLower
     // but this does not, because it looks for a UFCS-capable 
symbol
         .map!(c => c.toLower)
     // but this does again
         .map!(c => toLower(c))

```
