Tcl Source Code

2013-01-04  Donal K. Fellows  <[email protected]>

	* generic/tclEnsemble.c (CompileBasicNArgCommand): Added very simple
	compiler (which just compiles to a normal invoke of the implementation
	command) for many ensemble subcommands where we can prove that there
	is no way for scripts to detect the difference even through error
	handling or [info level]/[info frame]. This improves the code produced

 * and within range.
