Although altering Tcl.n is fraught with danger, nevertheless the following three improvements seem
appropriate:
1. Modify rule 1 to clarify the two phases of Tcl execution.
2. Modify rule 7 to clarify the ${} syntax and how it interacts with array variables.
3. Change the quotation marks to the neutral double quote character ("). This is consistent with
Tcl's Unicode, I18N, and cross-platform focus.

The change to clarify the two phases of Tcl execution was made to rule 2, not rule 1.
Lowered priority, since the old Tcl.n has worked for years.
