It is a fair rationale, but is there a reasonable implementation?

indent-tabs-mode is unknown by my emacs (21.2.1).

How do you keep tabs from appearing in MLton source code, but allow a
developer to use tabs freely in other projects/documents?  How do you do
this without requiring a developer to use Emacs?  Will my Emacs
auto-indentation for formatting still work?
