Tests of bool.while with iteration over a tuple

[c71n93]

There is no tests of bool.while that iterates over a tuple.
I ran into the problem of iterating over a tuple, and I didn't find a single working example in tests. I think we need to add some tests to eo-runtime/src/test/eo/org/eolang/bool-tests.eo.
@yegor256 @maxonfjvipon WDYT?

@yegor256 @maxonfjvipon What about this? Can I write some tests for while?

[maxonfjvipon]

@c71n93 sure, you can, especially if your tests will break something

@c71n93 the puzzle #2818 is still not solved.

[maxonfjvipon]

@c71n93 still an issue?

[c71n93]

@maxonfjvipon no, tests in while-tests.eo are pretty good, thanks!
