Namespace support

Itcl allows namespaces to be used for organizing commands and variables.

Example:package require Itcl itcl::class Toaster { variable crumbs 0 method toast {nslices} { if {$crumbs > 50} { error "== FIRE! FIRE! ==" } set crumbs [expr $crumbs+4*$nslices] } method clean {} { set crumbs 0 }} itcl::class SmartToaster { inherit Toaster method toast {nslices} { if {$crumbs > 40} { clean } return [chain $nslices] }} set toaster [SmartToaster #auto]$toaster toast 2
