Tcl extensions

'Language' utilities that extend and customize base Tcl.

Language features

fn {name args body}: creates a lexically scoped function in folk Example:

fn text {coords text angle} {
    Display::text [lindex $coords 0] [lindex $coords 1] 2 $text $angle
}

forever { ... }: Works like while true { ... }, but yiels to the event loop, so it's safe to use in the context of folk
assert { condition }: if condition evaluates to not true, it will error out and return the error code

python3 { ... }: evaluate the body in python3
lenumerate { list }: enumarate over a list, that is, return each of the elements in the list in the form { index element }
ltrim { list }: remove empty items at the beginning and the end of the list
undent { msg }: trims the indentation from msg, as long as it is made of spaces

language.tcl brings all of ::tcl::mathop and ::tcl::mathfunc into the global namespace.
