A list of things the @property tag does can be found here:
https://dlang.org/spec/function.html#property-functions
This behavior is particularly useful for generic code:
"For the expression typeof(exp) where exp is an @property
function, the type is the return type of the function, rather
than the type of the function."
Before I knew about this, I wrote this template to get the type
of 'field', because typeof(field) would return 'int()' instead of
'int' when it was a getter function without @property.
```
template ReturnOrValueType(type)
{
static if (isSomeFunction!(type.field)) {
alias ReturnOrValueType = ReturnType!(typeof(type.field));
}
else {
alias ReturnOrValueType = typeof(type.field);
}
}
```
