Re: "detect if anyone is anyone"
"Oddly enough "anyone" isn't in the OED."
It's in the macOS Dikshunry, which I thought was based on the OED.
Its entry contains this note on usage:
usage: The two-word form any one is not the same as the one-word form anyone and the two forms cannot be used interchangeably. Any one means ‘any single (person or thing)’, as in: not more than twelve new members are admitted in any one year.
