enterwrite is not OA_DANGEROUS
OA_DANGEROUS indicates that temporary copies may need to be made in
list assignment, to handle things like:
($a, $b) = ($b, $a);
In other words, an op type is flagged with OA_DANGEROUS if its return
values could occur elsewhere on the stack.
‘write’ only ever returns a read-only true or false, so temp copies
are not necessary for its sake.
