'''[TIP] [http://www.tcl.tk/cgi-bin/tct/tip/424.html%|%424], improving
`[exec]`''', by [Alexandre Ferrieux], proposes a new syntax for `[exec]` (and
by extension, to `[open]`) to make it possible to pass arbitrary values, even
those that look like special `[exec]` operators, as arguments to the executed
program.
