Stringbufs and bytevectors are now always "inlined" in the BDW-GC branch [0, 1], which means that there's no cell->buffer indirection, which greatly simplifies code (it also takes less room and may slightly improve performance). The `scm_take_' functions for strings/symbols/bytevectors are now essentially aliases to the corresponding `scm_from_' because we cannot advantageously reuse the provided storage. Should these functions be deprecated or discouraged? Thanks, Ludo'.
