* fix: perform send channel action for select The CFG was wrong for select send comm clauses. If an init operation on channel was required (like a derefence, index operation, ...) it was skipped. The bug was invisible in case of a local var channel. A send channel init operation consist to prepare both the data to send (right subtree of send AST) and the channel itself (left subtree of send AST). All channel init operation must be performed prior to call select. Fixes #647. * doc: fix comment * invert test to continue early please note that this also changes the logic a little bit, since the line that was: if pn != nil { now implictly becomes: if an != nil && pn != nil { (which I think is actually more correct). * explicit chaining of init actions in select * explicit chaining of init actions in select Co-authored-by: mpl <mathieu.lonjaret@gmail.com>
