That explains why X11.app launched that one time I forgot a `$` before my `x`...

That sounds likely. Note that is strictly for interactively typed commands. Witness:

  kamloops$ cat ls.tcl
  #!/usr/pkg/bin/tclsh8.6

  ls foo

  kamloops$ ./ls.tcl 
  invalid command name "ls"
      while executing
  "ls foo"
      (file "./ls.tcl" line 3)
  kamloops$ tclsh8.6
  % source ls.tcl
  invalid command name "ls"
  % ls foo
  foo
  % 

Now, back to your regularly scheduled Lua topic :)
