You might use the list::ToArray() method, and throw the error :

IDL> help, (list(indgen(2,2),indgen(3,3))).ToArray()
% LIST::TOARRAY: Unable to concatenate arrays: Element 1
% Execution halted at: $MAIN$

while :

IDL> help, (list(indgen(2,2),indgen(2,2))).ToArray()
<Expression> INT = Array[2, 2, 2]

Cheers,
