When is static is deprecated?

Under what cicumstances is the keyword "static" (?:not)? deprecated?

IIRC, to declare a function for use only in the translation unit where
it's defined. The Standard recommends the use of anonymous namespace
for that. There is a difference there (static function has internal
linkage), but the result is basically the same: the symbol's name is
not known outside the translation unit.

Thanks for the concise explanation!

So, even when I declare the internal functions of a module in an
anonymous namespace, they have external linkage? Do the extra,
externally linked symbols slow the typical linker? If so, is there any
non-deprecated way to declare functions that do *not* have external linkage?

Yes.

Not significantly, I'd think.

Not accessible from all scopes in a translation unit. You could define
an internal to a function class, members of that class don't have linkage
IIRC.

That's a good idea, but then those classes can't be arguments to
templates that are defined outside the function, right?

Yes.
