`Cell ::= $1 … · Cell(x)` Cells and holes

A rule with holes. $1 is filled by the first argument, $2 by the second. When there are more arguments than holes, the cell repeats to use them all.

A reference passed as an argument spreads into its items.
Without a hole, Name(a b) is an anchor application instead.

A rhythm applied to a line: one call, eight notes.
