Macro mentat_core::interpose

macro_rules! interpose {
    ( $name: pat, $across: expr, $body: block, $inter: block ) => { ... };
}

A helper macro to sequentially process an iterable sequence, evaluating a block between each pair of items.

This is used to simply and efficiently produce output like

  1, 2, 3

or

x = 1 AND y = 2

without producing an intermediate string sequence.
