Status: Closed
Resolution: None Priority: 2 Submitted By: Frank Barknecht (fbar) Assigned to: Miller Puckette (millerpuckette) Summary: Sending a list to [select] can leave it in an unusable state
Initial Comment: A [select] object primed with a symbol argument will reset itself into an unusable state by sending it a list with at least two elements.
Attached patch illustrates this behaviour using a [select x]-object. Sending a message [symbol x( will normally make the left outlet generate a bang. However sending a message [list x y( will disturb the [select x] object, so that it will not correctly react to a second [symbol x( message, until reset by a [symbol x( message to its rigth inlet.

I agree, lets just close it. But as [select] doesn't always have two inlets, this distributing of lists for [select something] may not be obvius to everyone.

It's not a bug.
This behaviour is consistent with many Pd classes, in which a list behaves like its $2 value goes in right inlet and then its $1 value goes in left inlet. This could be called "the implicit [unpack] rule", except that it's not necessarily as type-crippled as the real [unpack] is.
By default, each object that doesn't have a listmethod defined will have a default one that performs the implicit [unpack], if i understand correctly.

I down-priorized this, as it's not a real bug, the documentation just doesn't mention what will happen if lists are sent to [symbol x].
I'd suggest to update the documentation to explain, that like many objects in Pd [select] distributes lists over its inlets as well, which has to be taken into account when looking for unusual behaviour.
