New experimental command added in ::[tcl::unsupported] on 2009-12-07.

    :   '''[tcl::unsupported]::yieldTo''' ''coroutine'' ?''arg ...''?

Docs forthcoming, for now just the tclcore thread at [http://aspn.activestate.com/ASPN/Mail/Message/tcl-core/3789015]

May only be called from within a [coroutine].

----
[AMG]: Why is this command named with an internal capital letter?  All other built-in Tcl commands (as opposed to utility procs) are named with multiple words (or abbreviations thereof) jammed together with no capitals or underscores.  Examples abound: [[[bgerror]]], [[[fblocked]]], [[[filename]]], [[[foreach]]], [[[gets]]], [[[lappend]]], [[[regexp]]], [[[uplevel]]], and [[[vwait]]].

[MS] no special reason
