Ticket #1014 (closed feature: wontfix)
NQP: Add defined(), exists(), undef.
|Reported by:||Austin_Hastings||Owned by:||pmichaud|
Testing using code like
if $foo ...
works until your class doesn't have a get_boolean, or until you are trying to see "if $foo is set" rather than "if $foo is true".
Then you need defined, or some kind of ==undef or !=undef test.
