+ TXR 122
+ 2015-11-05
+
+
+ Features
+
+ - New type: range.
+ - range is similar to a cons cell, but is an atom.
+ - has two fields called from and to.
+ - the dotdot syntax a..b now produces a range, not a cons.
+ - printed notation looks like #R(0 10)
+ - related functions: rcons, rangep, from, to.
+
+ - sys:capture-cont API altered to call/cc style: passes
+ continuation to specified function when capturing,
+ returns value when resuming.
+
+ - New interface to delimited continuations: suspend macro.
+
+ - TXR pattern variables now appear dynamic to embedded Lisp
+ expressions, rather than lexical. The scoping rule is
+ documented.
+
+ - The yield and yield-from operators can omit the argument
+ form, in which case they retrieve the value passed in from
+ the resume function without yielding an item.
+
+ - Architecture support: Power PC 64.
