Hi, can we somehow provide an array of reifications to a metalink metaobject ? For ex.: link metaObject: [:args| do stuff with args]. link selector: #valueWithArguments:. link arguments: #(object node link receiver sender) So that when the link executes, args in the block would be an array containing all wanted reifications ? This example does not work as is, because the number of reifications (5) is different from the number of arguments taken by the selector (1). The problem is that for blocks, i could use the #value: message, but it is limited to #value:value:value:value:, so 4 arguments. Besides, if i want 10 reifications for example, i would not want to have a selector like #value:value:value:value:value:value:value:value:value:value: ... Any ideas ? Steven.
