Like `n⋆0` gives the multiplicative identity `1`, `F⍟0` is the compositional [identity](identity.md), `⊢`. Since `F⍟1` applies `F` and `F⍟0` doesn't, Repeat might be pronounced "if" or "conditional" when `𝔾` is boolean. -BQN's Repeat modifier has some extra functionality relative to the mathematical version. It allows a left argument, and some extensions to the right operand `𝔾`. As usual for 2-modifiers, `𝔾` is actually a function that applies to the arguments to give a result. The result can be a natural number as shown above, or a negative number to Undo (`⁼`) `𝔽`, or an array of values. +BQN's Repeat modifier has some extra functionality relative to the mathematical version.
