I'm sorry, I'm not familiar enough with the indentation rules you're referring to; could you explain it more throughly? This might be a case where I accidentally solved a problem ;).

Haml expects that where there is to be indentation, that indentation is to be exactly 2 spaces. Not 1, not 3, or 4, but 2. It isn't enough that a line start in a new column further to the right, it has to start in a very specific column relative to its parent.

However, there are cases where the content is such that I want to emphasize it or offset it in some way using whitespace.

My experience has been that this isn't allowed.

Oh, I'm certainly glad I strayed from the Haml specs then! Hamlet allows arbitrary indentation. In fact, some might argue that the indentation rules are *too* lax, but we'll let experience be the deciding factor on that.

Basically, here's the rules:

* a tab is 4 spaces. I considering not allowing tabs at all, but hopefully people know not to mix spaces and tabs already.

* each line has its indentation level calculated

* a line is nested within the first line above it with a lower indentation level

I actually think that sums things up completely. I have just added a page[1] on the documentation site to explain these rules, thank you for pointing out that it was lacking.
