Consistent Metafunction Aliases
by Michael Park
This paper recommends a systematic guideline to steer future WG21 decisions in deciding when a metafunction-name
_ttemplate alias should accompany a standard library metafunction. After applying this recommended guideline to the entire C++14 standard library, we conclude that
tuple_element_tis the only missing alias. We then propose wording (a) to remedy this lack and (b) to take advantage of the proposed remedy. Finally, we also present an alternative guideline and its implications, and provide justications for favoring the recommended guideline.
