  #lang planet plai/plai:1:8/mutator

produces this error message

  #%module-begin: bad syntax in: (#%module-begin)

but would be better if it said ""expected ..."" and gave me a schematic of the expression it expected to find there. Similarly, these programs all produce bad error messages:

  #lang planet plai/plai:1:8/mutator

  #lang planet plai/plai:1:8/mutator
