In the tutorial I'm learning pd in (it's a few years old), the instructor stresses connection order to insure the functions fire as intended. I double checked this with a list (changing the order I connected the values in the list) and I experienced no difference when I printed it.

Is this a special property of the list (pack) function? or does connection order not matter anymore? (meaning triggers can safely be more rarely used)

Update: I just changed the connection order, not with a list but just having a bang directly print 4 different values. The value order that they printed was determined by the sequence that I added them to the bang button. So I see now the pack function orders the list according to the first inlet to the right inlet.

you really should use [t ] to ensure execution order is clear
