[plt-scheme] In-line LaTeX in REPL

Hi All,

First of all: This is brilliant.

  A small observation: At first the shell that DrScheme starts couldn't find
  any of pdflatex, convert, and gs since they weren't on the path.
  (I normally use spotlight to start DrScheme)
  Starting DrScheme from a terminal solves all of this.

Last, but most importantly:

I saved Eli's version in latex.ss

> #reader scribble/reader
> #lang scheme
> (require scheme/system scheme/gui/base)
> ;; Examples
> @latex{\sum_{i=0}^{\infty}\lambda_i}
> (let ([self @str{\lambda x . x x}])
>   @latex{(@self) (@self)})
And the I run them I get nice formulas in the REPL.

But! If I enter the following in the REPL

  (let ([self @str{\lambda x . x x}])
    @latex{(@self) (@self)})

I get the following error from the reader:

    read: illegal use of `.'

Should the REPL of the module language use the reader
specified in the source file?
