Moreover, export dynamic and import dynamic don't have fname or cid.

foreign import dynamic is a shortcut for importing an automatically
generated C function which could be easily written by hand. It fits
well into regular imports with a single distinguished magical extent.
All parameters are in the type, so it can be called "dynamic" or
"curry" or "apply" or whatever, perhaps with special characters to
distinguish the name from plain functions.

foreign export dynamic is a shortcut for importing an automatically
generated nontrivial C function, with argument type not conforming to
regular imports, which could not be written by hand. So it's actually
an *import*! It could be spelled as import with a magical name - again
all parameters are in the type.
