### Fixes * Added `===` at the end of integrated help descriptions (#127). * Fixed override propagation when setting isymbols in upper scopes (#133). ### Mew additions * New symbol: [parent-scope](https://min-lang.org/reference-lang/#op-parent-scope) (#117). ### Notable changes #### Lambda capturing in operator output values You can now specify a lambda to be captured to an output value, like this: ( symbol square (==> quot ^o) ( (dup *) ~o ) ) :: Essentially, this allows you to push a lambda on the stack from an operator. Note that: * Lambdas must be captured using the `^` sigil in signatures and bound using `lambda-bind` in the operator body. * Lambdas cannot be captured in input values (they have already been pushed on the stack). * Requiring a lambda as an output value effectively bypasses stack pollution checks. While this can be useful at times, use with caution! |
