Reasons that spring to mind include:

  - functional languages are not inherently well-suited to
  outputting partial results, or having side-effects. A standard
  function provides a single answer, nothing more nor less. Of
  course, it is possible, and extensions/libs have made it much
  easier.

  - ...But it's a little like wondering why no-one has written an
  OpenGL-based 3D engine in pure assembler, without any recourse to
  C, C++ or etc - why on earth would you do it? Functional languages
  certainly have uses in some branches of AI and parsing, but in
  what ways are they suited to MUDs?

OTOH, I too would be surprised if no-one, ever, has done a MUD in an
fn-language. I'm pretty sure I'd heard of at least one, somewhere...
