That's the question being posed. =)
A quick browsing of the grammar shows us already using 'in', 'as',
'from', and 'else' as keywords that are keywords which are not
statements as their own ('in' is unique, as Guido pointed out because
of its use with 'for' and as an operator).
Something like ``assert _expr_ else _message_`` might work, but I am
not sure if people will misunderstand the meaning of 'else'. But if
does somewhat match the usage with 'if' expressions as the expression
following is not executed if the preceding expression is true.
