```D
class bitmapHandler
{
bitmap*[string] bmps;
void get(string name){return bmps[name]; /* plus other code */}
}
void usage()
{
bitmapHandler bh;
bitmap foo = bh.get("bar"); // works
bitmap foo2 = bh["bar"]; // desired
}
```
Should I be using opEquals? Or something different? The problem
with 'alias this' here is I want to wrap access to the insides
with getter functions that do various things like logging and
error checking.
I mean, if I ruined some encapsulation, I could make a function
called "bh" and have the usage:
```D
bh("bar");
```
and have it access a singleton object.
