I don't understand why you'd need to expand to 'some' expressions.
Why not just replace
.=$arg2
with
try { .=$arg2 } catch err:XPTY0004 { false() }
Or, for better encapsulation, replace it with
my-equal(., $arg2)
where 'my-equal' has the semantics that Option 1 would give to '=':
declare function my-equal(...) as boolean()
{
try { $arg1 = $arg2 } catch err:XPTY0004 { false() }
}
