The State of TclQuadcode 2017

The 'tclquadcode' system is a compiler, now under development for about three years, that translates a significant subset of Tcl to machine code. For the limited cases that it can handle, 'tclquadcode' produces significant gains with respect to the bytecode engine: 4-6-fold speedup in the typical case, and 30-100-fold speedup in the most advantageous cases. This talk presents recent work on speeding up the interface between compiled and interpreted code, avoiding memory allocation, and supporting non-local variable references. The speakers also intend to poll the audience informally on several topics where quadcode may drive developments in core Tcl.
