Stylus not parsing some directives

Question

Using the Stylus / Jeet's column() or col() mixins, some are not compiling, but showing up literally in my generated css files. This should not be happening.

Test.styl

@import 'jeet'

#main
    center(1000px)

#content
    col(2/3)

#sidebar
    col(1/3)

Generated test.css snippet

#content,
col(2/3), //<- This shouldn't be here
#sidebar {
   ...
}
#content:before,
col(2/3):before, //<- or this
#sidebar:before,
#content:after,
col(2/3):after, //<- this too
#sidebar:after {
  content: '';
  display: table;
}

Answer 1

Repeat after me: Don't mix tabs and spaces for indenting.

Looking at non-printable chars in my .styl file led me to the problem:

#main
{\t}center(1000px)

#content
{\b\b\b\b}col(2/3)

#sidebar
{\t}col(1/3)

Stylus was correctly parsing the majority case (tabs) and not parsing the edge case (spaces).
