product/arithmetic each: missing block nil.
* stdlib/arith-each.tl (sys:vars-check): New function, copy and pasted from each-prod.tl. (sys:arith-each): New macro. (sum-each, sum-each*, mul-each, mul-each*): Reworked using sys:arith-each macro. This macro uses logic borrowed from a stripped-down expand-each in the compiler. * stdlib/each-prod.tl (sys:expand-each-prod, sys:expand-arith-each-prod*): Add the block nil around the mapping call, taking care that the initialization forms are evaluated outside of the block, and their values bound to gensyms that then form the function arguments. * txr.1: Document the missing requirements for all the affected macros that there must be an anonymous block around the body, which, if used, determines the return value.
