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...
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...
otherwise executes in the (wrong) context of the invoking Workbook (and probably returns #REF!). NB: My Excel is tuned to the European convention and I hence normally separate function arguments with ";". However, VBA does not alter its syntax depending on locale. Since EVA...
