in reply to Strange bug with map

That isn't a bug with map, it might be a bug with getObservations, maybe it assigns undef to  $_[0] or $_ which will affect the values

    Good point.

    Most likely, the "sub getObservations{}" modifies $_ , which would upset the values in the "map" case, where he uses "$_->getObservations() ".

    In the "for" loop, he uses "$docP->" as the alias for the values, so modifying $_ inside "sub getObservations" will not change the values.

    The fix would be to "local $_" inside "sub getObservations{}" where necessary.
