Locals are a leaky abstraction. The leaks should be fixed as much as possible. [factor{! Fry and locals
[ is-integer? ] [ is-even? ] [ >10? ] } && ] ; [ f ] [ 1.5 wlet-&&-test ] unit-test [ f ] [ 3 wlet-&&-test ] unit-test [ f ] [ 8 wlet-&&-test ] unit-test [ t ] [ 12 wlet-&&-test ] unit-test

. On the left hand side, they should bind locals.
[ 10 ] [ 0 '[ [let | A [ 10 ] | A _ + ] ] call . ] unit-test
Locals and macros which treat quotations as sequences
:: (funny-macro-test) ( obj quot -- ? ) { quot } 1&& ; inline : funny-macro-test ( n -- ? ) [ odd? ] (funny-macro-test) ; \ funny-macro-test must-infer [ t ] [ 3 funny-macro-test ] unit-test [ f ] [ 2 funny-macro-test ] unit-test
