Follow-up Comment #2, bug #37179 (project octave):

The problem isn't even with isequal.  The issue is that the parser immediately
tries to find the function handle @XXX in the symbol table and when it fails
it reports an error.  You can verify this by setting a breakpoint in the
function isequal and you will find that the breakpoint is never reached.  

Perhaps the answer is to delay the lookup on a function handle unless a value
is requested.  Thus,

y = @sin;  # Assign the function handle @sin to y without looking it up
y = @sin(1); # This would cause the function handle lookup.
