George Peter Staplin: July 10, 2004 - It sometimes amazes me how beautiful some aspects of Tcl are. I've been using proc unknown args {expr $args} for a while for doing calculations and tests when designing software. Today it occured to me that I could make life easier and avoid so many parentheses by extending that simple unknown procedure to this:
proc unknown args {set ::that [expr $args]}Now I can do:
$ echo "proc unknown args {set ::that [expr \$args]}" > .tclshrc
$ tclsh8.4
% 1000 * 256
256000
% $that / 8
32000
