That should be:

TypeInfo mytype = typeid(int);

typeid() returns a type's TypeInfo at runtime. typeof() infers the type 
of an expression at compile-time.

Note that TypeInfo is just information about a type. (You can compare 
the TypeInfos of two items to see if they are the same type.) You cannot 
create variables of a type with just its TypeInfo. (That kind of 
trickery is what templates are for.)
