I've seen some tags that are referencing specific functions within a programming language. However, these functions are only defined in the one programming language (AFAIK), and I'm wondering if these sorts of tags are appropriate for SO.
Most of these tags don't have a wiki and have few questions attached to them. Almost all of them are appropriately tagged with the language that defines the function.
Examples include (I hang around in php):
So, are these tags relevant and appropriate for SO, or are they just adding clutter?
Edit: There is also a lot of ambiguity here, for example:
- simplexml-load-file is a tag, simplexmlloadfile is not, yet simplexmlelement is.
- inarray and in-array both exist.
- numberformat and number-format both exist.
- dateformat and date-format both exist (very ambiguous, has implications in Java while still being the name of a PHP function)
Maybe these tags are best suited as synonyms. However, I think more needs to be done than just "allowing all tags whose names match functions", even if it's just establishing a best practice.
Edit: There's even more obscurity here, as the following tags exist:
