Tuple not converted to list

[Bruce Sherwood]

I  thought it was the case that tuples are always converted to lists, but not in this (admittedly unusual) case:

d = {}

d[(1,2)] = 'cat'

d[(3,4)] = 'dog'

transpiles to

d = { };

d[[1,2,]] = "cat";

d[3, 4] = "dog";  // note that [(3,4)] has been converted to [3,4]

This bug is present in the newest RS as well as in earlier versions.

Ah yes, you're correct about the last case. I will take a look at it. However, you're saying that d[(1,2)] compiles to d[[#,#]], and d[(3,4)] does not? I'm seeing them both compile to d[#,#], and in fact that's what I'd expect - there is nothing in second case that would cause the tokenizer engine to interpret the two differently and I'd be concerned if it did. Are you sure there wasn't a typo? This is what I'm seeing for compiled output:

var d;

d = {};

d[1,2] = "cat";

d[3,4] = "dog";

You're right -- there's an unfortunate typo in my input code, which was supposed to read like this:

d = { };

d[ [1, 2] ] = "cat";

d[ (3, 4) ] = "dog";

which transpiles as I said to

d = { };

d[[1,2,]] = "cat";

d[3, 4] = "dog";

Sorry for the confusion!

I'm reminded of the wonderful Monty Python skit in which an auditioning singer sings "You say tomatoes and I say tomatoes, you say potatoes and I say potatoes; tomatoes/tomatoes, potatoes/potatoes, let's call the whole thing off", in which he pronounces the supposedly different pairs exactly the same. Eventually he stops and says, "I don't see what their problem is!"

Here's a simpler case:

a = ((1,2), (5,2), (8,4)) # compiles to a = [1,2,5,2,8,4,]; but presumably should be [[1,2], [5,2], [8,4],]

b = [(1,2), (5,2), (8,4)] # compiles to b = [[1,2,],[5,2,],[8,4,],];
