An @code{if} expression is a conditional branch in program control. The form of
an @code{if} expression is a parenthesized condition expression, followed by a
consequent block, any number of @code{else if} conditions and blocks, and an

an @code{if} expression is a condition expression, followed by a consequent
block, any number of @code{else if} conditions and blocks, and an optional

@code{bool}. If a condition expression evaluates to @code{true}, the
consequent block is executed and any subsequent @code{else if} or @code{else}
block is skipped. If a condition expression evaluates to @code{false}, the
