For immediate blocks, this is the only type of header possible, and it must use an identifier as there is no applicable special name. However, this name can't be used, except for returns: it doesn't make sense to refer to a value while it is still being computed!

Multiple bodies

Blocks that define functions and deferred modifiers can include more than one body, separated by semicolons ;. The body used for a particular evaluation is chosen based on the arguments the the block. One special case applies when there are exactly two bodies either without headers or with labels only: in this case, the first applies when there is one argument and the second when there are two.

This is the main drawback of predicates relative to guards in APL dfns (also written with ?), while the advantage is that it allows multiple expressions, or extra conditions, after a ?. It's not how I would have designed it if I just wanted to make a syntax for if statements, but it's a natural fit for the header system.

Returns

-

This feature is not yet included in any BQN implementation.

-

The glyph → indicates an early return from a block. It must be preceded either by one of the self-reference special names 𝕊 or 𝕣 or by an internal name for a containing block. The combination of name and return token—like F→, let's say—is a function that returns from the current instance of the indicated block. If that instance has already returned, then it instead results in an error.
