The keyword ti(typedef) is still used in bf(C++), but is not required
anymore when defining  ti(union), ti(struct) or ti(enum) definitions.
This is illustrated in the following example:
        verb(    struct SomeStruct
    {
        int     a;
        double  d;
        char    string[80];
    };)

When a tt(struct, union) or other compound type is defined, the tag of
this type can be used as type name (this is tt(SomeStruct) in the above
example):
        verb(    SomeStruct what;

    what.d = 3.1415;)
