Next Expression

next-expression ::= 'next'

Skips the remaining portion of the loop body of the enclosing while expression or for expression and starts a new iteration. In other words, a next expression is semantically equivalent to transferring control to just after the final statement of the loop body.

Any defer statements that would go out of scope due to the control transfer are executed before the next loop iteration is started.

It is a semantic error for a next expression to appear outside of the loop body of a while expression or for expression. If a next expression appears in the body of a defer statement, it cannot bind to a while expression or for expression outside of the body.

A next expression has no result value.
