'''tcl::mathop''' is a Tcl 8.5 [namespace] that contains commands equivalent to the [expr] operators. These commands are all bytecode compiled. Note that changing or adding to these commands does ''not'' change the [expr] operators themselves.

See [Math Operators as Commands] and [tcl::mathfunc]

----

A simple example, because I couldn't immediately work out the incantation to make mathops visible. Note that functions and operators come from different namespaces:

  namespace import ::tcl::mathop::*
  namespace import ::tcl::mathfunc::*
  puts [* [sqrt 49] [+ 1 2 3]]

Alternatively:
  namespace path {tcl::mathop tcl::mathfunc}
  puts [* [sqrt 49] [+ 1 2 3]]

There are better examples of the use of mathop scattered through the wiki; somebody should add links to some of the ones less obvious to non-lispers!
