We treat \code{-$l$} \emph{as if} it is a single integer literal with a negative
|
||||
numeric value. The specified semantics of integer literals (\ref{numbers})
|

allows negative numeric values, so they can be applied as-is to the value $-i$,
|

except that we want \code{-0} in a \code{double} context
|
||||
to evaluate to \code{-0.0}.
|
||||
The expression \code{-$l$} is not \emph{itself} an integer literal,
|
||||
it's merely treated as one,
|
||||
so this rule does not apply twice to \code{- -$l$}.
|
||||
It also does not apply to \code{-($l$)}
|
||||
since a parenthesized expression is not an integer literal expression.
|
||||
We treat \code{-$l$} \emph{as if} it is a single integer literal
|
||||
with a negative numeric value.
|
||||
We do not evaluate $l$ individually as an expression,
|
||||
or concern ourselves with its static type.
