Drifting back toward the original subject, I'm reminded of the non-bsd-c
idiom of
char *foo(char *p) {
if (p != NULL && *p != NULL) {
return some string operation...
}
...
It seems logical to check the type of the contents of an interface
type, and its presence in a function that can take nil types and
nil contents, much as in the C idiom.
Mind you, I do find type assertions a bit clunky.
