Due to the declarative nature of~TAME, recursive operations
needing to step are~not all that common. These operations are
useful when converting between 1-indexed and 0-indexed data.
\ref{_inc_} increments a value by a~single step (default~1).
1
\ref{_dec_} decrements a value by a~single step (default~1).

Negation is a common task and it was tedious in older versions of
TAME\footnote{Before it was even called TAME, actually.} For
these situations, \ref{NEGATE} is provided to avoid having to use
a~\ref{const} expression. To avoid a {\tt product} expression
altogether, use~\ref{_negate_}.
