Tabs wouldn't be a problem so long as they are used consistently (one
tab per indentation level).  Given two whitespace sequences A and B,
there are four possibilities:
  - They are identical, so they represent the same indentation.
  - A is a prefix of B, so B represents the deeper indentation.
  - B is a prefix of A, so A represents the deeper indentation.
  - Neither is a prefix of the other, which would be a syntax error.
