The .byte_stack is used only by files to: a) unread a single octet when we use fallback LISTEN implementation b) unread bytes that make a character when UNREAD-CHAR is used The latter is important to transcode characters from one external format to another (i.e see the test external-format.0003-transcode-read-char). This commit improves the function unread-byte to do the same brinding bivalent streams almost to parity with regard to that implementation (see next commit). That makes the implementation of eformat cleaner, .byte_stack more self-contained, and saves us consing new byte stack for sequence streams (where it was simply ignored, not to mention not entirely correct - because we've used a .byte_stack length to decrement the pointer position while the byte could have more bits than one octet). Other optimizations that could be done here: - make the byte stack an adjustable vector to avoid consing on each unread |
