Let's say this keyword throws away everything in the lexical scope, except for what you declare sub compute-G (\a, \b, \c) { my \d = only-use ( a, b, :<+>, :<*>, :<**> ) { a + b * 2 ** 3 } … return g; } I think that would get old real quick. On Fri, Dec

Re: [perl #131599] [BUG] "my %hash is default([])" misbehaves

There does appear to be a bug, but I'd argue that it is in your code. my %sum{Int} is default([]); That line of code sets the default for all elements when they are first accessed to the very same instance of an Array. Remove the `is default([])` To stop the warnings that would then happen

Re: How do you call the variable types?

@ does the Positional role % does Associative & does Callable $ causes its value to be an item (its values do not flatten into an outer list when you use `flat`) my %hash is SetHash; Array does Positional, and all of its values are itemized We are unlikely to call $ variables "generic"

Re: need help with "next"

You do realize that `next` immediately stops the current iteration and goes onto the *next* one right? That is, there is no point putting any code after it because it will never be run. On Tue, May 23, 2017 at 11:30 PM, ToddAndMargo wrote: > Hi All, > > I have a test code
