Yes, templates. I've looked this up a bit, and I found it. I want to use it to use the dictionaries for different things than string<->int conversion.
T is just the common name of a (type) parameter, mostly whenever the template is more generic that you can't think of a more informative (template) parameter name. Just like you could use "str" for a string or "i" for an int name. But in you case you could use a more informative name such as "keyType" since you are describing keyType -> valueType dictionaries, also called associative arrays.
Moreover these dictionaries are built-in basic types in D: https://dlang.org/spec/hash-map.html
This should be the Dictionary(int), string<->string conversion should be done with Dictionary(string). Int<->string should be done as Dictionary(string,int) if possible.
So according to the spec linked above, those examples would be declared:
string[int] dict1; string[string] dict2; int[string] dict3;
