+ TXR 254
+ 2021-03-10
+
+
+ Features:
+
+ - compiler:
+ - elimination of function calls that produce unused values.
+ - this compiles down to just "nil":
+ (let ((x (cons y z))) (set x (cons u v)) (set x nil) x)))
+ - elimination of unused accesses to globals
+ - elimination of unused lambdas.
+ - optimization control: new variable *opt-level*, valued 0-6.
+
+ - lib:
+ - new functions join and join-with to complement the tired old
+ cat-str for joining strings and characters.
+ - (join-with ":" "a" "b" "c") -> "a:b:c"
+ - (join "a" "b" "c") -> "abc"
+
+ Bugs:
+
+ - broken sort function over vectors and strings
+ - failing to return the sorted object
+
