- Create the stencil name using targ.Type.String(), which handles cases where, for example, a type argument is a pointer to a named type, etc. *obj. - Set name.Def properly for a new stenciled func (have the symbol point back to the associated function node). Will be required when exporting. - Add missing copying of Func field when making copies of Name nodes. (On purpose (it seems), Name nodes don't have a copy() function, so we have to copy all the needed fields explicitly.) - Deal with nil type in subster.node(), which is the type of the return value for a function that doesn't return anything. - Fix min to match standard want/go form, and add in float tests. Changed Got -> got in bunch of other typeparam tests. - Add new tests index.go, settable.go, and smallest.go (similar to examples in the type param proposal), some of which need the above changes.
