mix()

mix([<object>/]<attribute>, <list1>, <list2>[, ... , <list30>, <delim>])

This function is similar to MAP(), except that it takes the elements of up to 30 lists, one by one, and passes them to the user-defined function as %0, %1, up to %9, respectively, for elements of <list1> to <list30>. Use v() to access elements 10 or higher. If the lists are of different sizes, the shorter ones are padded with empty elements. <delim> is used to separate elements; if it is not specified, it defaults to a space. If using more than 2 lists, the last argument must be a delimiter.

Examples of mix():

> &add_nums me=add(%0, %1)
> say mix(add_nums,1 2 3 4 5, 2 4 6 8 10)
You say, "3 6 9 12 15"

> &lengths me=strlen(%0) and [strlen(%1)].
> say mix(lengths, some random, words)
You say, "4 and 5. 6 and 0."

> &add_nums me=lmath(add, %0 %1 %2)
> say mix(add_nums, 1:2:3, 4:5:6, 7:8:9, :)
You say, "12:15:18"
