[Vala] Foreach on lists (bug #645850)

[Maciej Piechotka <uzytkownik2 gmail com>]

Hi,

Are there any plans of solving #645850? The current (since April 2011)
Vala behaviour is bad for any list but ArrayList. In some cases it
alters not only performance but behaviour (see ConcurrentLinkedList
example).

At least for libgee 0.8+ it can be fixed by transforming loops into
lambdas and passing to foreach. The benchmarks are attached.

Best regards
