Language
A sequence of expressions separated by semicolons and optionally terminated by a semicolon are a single expression whose value is the value of the last expression. Such a sequence may be used anywhere that a normal expression may be used.
@racketblock[
max( b = a * 2; b + 5, 10); // computes the maximum of b+5 and 10
::
In the above example, the sequence: ]
@racketblock[ b = a * 2; b + 5 :: acts as a single expression for the first argument to ]
@racketblock[max()::.
]
