* sgc: refactored implementation to permit new features
* sgc: small improvements
* sgc: SGC is nestable and can be collected by parent sgc's
* sgc: reduced overhead, made drop functions chainable
* sgc: more testing
* sgc: added bindings and removed cruft
* sgc: improved implementation, supporting free and realloc
* sgc: simplified realloc logic
* small improvements to header
* check-in sgc runtime
* compiler.target.C: more repair work, though not yet finished.
* compiler.target.C: partially fixed formatter and refactored interface to avoid unnecessary string copying * core: `zarrayof&` form can be used to build (constant) string arrays from a fixed number of single chars * print: `/char ...` prints individual chars like a string
* more work on C backend
* more work on C backend
* initial port of compiler.target.C.format to C++
* checked-in Allocator module
* Array: added custom allocator support
* syntax now supports symbol literal prefixes; e.g. `xy'z` is turned into `prefix:xy\' "z"` * `char` string prefix now also supports symbol prefixes, and char lengths up to 8
* compiler.MappedFile: renamed array interface * testing: added BDD.sc to various
* MappedFile: added `MappedArray`, a dynamic array implementation that mirrors directly to a file
