If tabs are used, not just an amorphous pile of spaces, then indentation
information exists in the file. Then, as partially described in
":h listchars", we can:

:set tabstop=2 sw=2 noexpandtab
:set listchars+=tab:>-
:set list

so that:

class Foo
def foo
x = 10
y = 12
end
end

gains a blue ">-" for each tab present. Visually scanning the columns of
">" is much quicker than counting dots. Changing the listchars to tab:!-
makes that even easier, I find. (Attempting tab:|- generates an error.)

If you have autoindent enabled, you will also see those ">-" appear.

To turn off the indication:

:set nolist

It may be convenient to map these on and off operations to e.g. F1,F2.

Is that close enough?
