or not at all. If a lambda expression has to access local variables and function parameters, they must be captured. The capture clause (lambda-introducer in the Standard syntax) specifies whether the body of the lambda expression can access variables in the enclosing scope by value or by refer...

Sometimes a lambda would be too unwieldy to extend much further than the previous example. The next example uses a function object instead of a lambda, together with thefor_eachfunction, to produce the same results as Example 1. Both examples store the count of even numbers in avectorobject...
letf (((symbol-function 'not) (lambda (x) x))) (yy-unless t (+ 1 2))) =>3 很明显,在动态作用域中宏里面的 not 指向了一个恒等函数,没有起到逻辑取反的作用。 从上面的例子中我们可以看到两个问题: 宏里面的东西可能在不经意之间对外部造成...

If you find having formulas on the worksheet distracting or ugly, you could wrap the whole shooting-match within a further Lambda to give =Indirectλ(function,ϑ) This is essentially the same approach that Sergei takes with SWITCH. It does not work when the target Lambdas are in a foreign...
