It will not work. Instantiation should be same for all types...

I found following solution:

void parse(T)() {
        static if (isAssociativeArray(T)) {
                ....
        } else {
                ....
        }
}

Template isAssociativeArray(T) is from Tango/core/traits.d. (Thank you, 
Tango team!). Thanks to this template I could also get key type and value
type of associative array.

Anyway I think that it should work somehow for specializations, so I will
put enhancement request on bugzilla.
