Hello,


For the following statement:

? 1={}

could there really be any interpretation other than to compare
every element of the sequence with the atom '1' ?
After all, we are not trying to compare what types the two
arguments are, we are trying to compare all the sequence elements
to the atom '1'.

In this example,

? 1={1,2,3}

the number 1 is compared to every element of the sequence, and
a sequence is returned with the results, and it must be a sequence
returned in order to show the results.  A single number like 1 or
0 would not indicate anything useful, and if we want to know what
type something is, we have 'atom()' and 'sequence()'.



Take care,
Al
