Number indices on table literals are not properly supported. Not only does the parser itself not have any logic for inserting variables into numeric indices, but the runtime also has poorly implemented logic that will always result in an out-of-bounds exception if native code tries to insert into them.

The proposed Ona script syntax for numeric indices in tables is as follows:

Table literal with numerically indexed elements only:

array_table = {0, 1, 2, 3}

Table literal with mixed numeric and field indexed elements.

mixed_table = {
	"world",

	greeting = "hello",

	"there",
	"everyone",
}

In order to support symbols, similar to Ruby, I believe this issue should be expanded to also include handling for symbols.

The new syntax proposal is as follows:

Table literal with numerically indexed elements only:

array_table = {0, 1, 2, 3}

Table literal with stringly indexed elements only:

string_table = {["foo"] = "bar", ["number"] = 42}

Table literal with symbolically indexed elements only:

symbol_table = {.foo = "bar", .number = 42}

Table literal with mixed numeric and field indexed elements.

mixed_table = {
	"world",
	.greeting = "hello",
	["language"] = "en",
	[5] = "there",
	"everyone",
}

Re-opening as #30 didn't end up solving this issue fully, only partially with the introduction of symbol indices.
