Out of curiosity what does the "." in front of `foo` mean?

The dot operator simply specifies that the symbol you are
looking for is defined at global scope, so it just changes the
lookup rules.
Even though it makes the code clearer what foo you are looking
at, it was not necessary -- removing the dot works.
In some cases it is necessary to use the . lookup rule, because
you have another symbol that will be picked first.
For example:
int x;
template bar(string x)
{
mixin("alias " ~ x ~ " = .x;");
}

Thanks both of you. It's one of those puzzling things that was at
the back of mind that has just been resolved.
