Arc is supposed to be a LFSP. Smart people adjust their user model to the tools they have available (right?), so it's at least consistent with Arc's design principles.

It's not the choice I would've made - I tend to agree with you that "explicit is better than implicit". But languages all have to make certain assumptions about who their users are (same with UIs, really), and this design decision is consistent with Arc's previously-stated design philosophy.
