The following examples in tutorial cause errors

Thanks to Ben Thomasson for correcting this for me the code should be
ALSO notice that one example is incorrect for -b passing a string 4 5 needs to be bound {4 5}

Dear John,
this example is correct for xotcl 1.3.5, which the tutorial tries to document (see Changelog). xotcl 1.3.5 accepts the "old" syntax with separate argument lists (as in your "corrected" version) and the new syntax with a single argument list, which i added for 1.3.5 to make non positional arguments more similar to what's used in openacs. Btw, xotcl's non-pos arguments implementation is by a factor of 6 faster than the tcl implementation in oacs (i.e. reducing the invocation overhead by this factor).

This was certainly incorrect in the tutorial. i have fixed this locally, and it will be fixed on the server in a few minutes.
Thanks a lot

PS: we are planning the release of 1.3.6 with a few bug fixes this week or early next week ... with windows binaries.
