Expand description
The optimize transform: replaces the dictionary-key argument of every
recognised caller with a pre-imported dictionary object and re-points the
import specifier at the matching *Dictionary helper.
Only the native useIntlayer / getIntlayer / getIntlayerAsync rewrite
lives here. Compat adapters plug in through ExtraCallerContext, held as
an Option: with no extraCallers configured it is None, every branch
guarded by it is skipped, and the native rewrite runs exactly as if the
adapters did not exist.
