      1/ in my opinion, the goal of good boundaries and isolation is to let you be "sloppy in the small, rigorous in the large"

      2/ Dynamic languages simply don't allow rigorous in the small, and that has great benefits in many ways.

      3/ Breaking isolation boundaries makes the "sloppy in the small" leak into the large and eventually slow you down.

      4/4 But if you have tiny isolation boundaries, you're just trying to recover "rigorous in the small", poor fit for dynlang.

      @wycats that's pretty insightful. As long as you're thinking about these things, maybe offer a simple definition of dynamic languages?

      @isaac32767 I think the answer is tautologous from the rest of my statements. Function boundaries offer insufficient tools for rigor.

          @isaac32767 it's easy to say "YAGNI rigor", but I think what happens in reality is that larger isolation boundaries take their place.

          @isaac32767 And I think that's fine. Sloppiness can be correlated with productivity in the small!

          @wycats not sure you understood my question. It was not meant to be an argument to your previous statements.

          @isaac32767 I just meant that the rest of the statements basically define "rigor" implicitly.

          @isaac32767 Every language has some details that cannot be expressed in various signatures. That "sloppiness" ends up being ok in the small.

          @isaac32767 JS doesn't even have arity checking, for example, while Ruby does. Go has structural types only, etc.

          @isaac32767 The sloppiness in each of these systems is ok as long as the implicit assumptions don't leak.

          @isaac32767 Isolation boundaries try to use human tools to contain the sloppiness, which works well if the boundaries are relatively coarse.
