Table.unpack() is interpreted as a variadic tuple instead of individual parameters, leading to code failure

[UMadara10 (IsThisErvum)]

local HTTP: HttpService = game:GetService('HttpService');

local t: { [number]: (string | (Enum.HttpContentType) | boolean) } = {
	'',
	(Enum.HttpContentType.ApplicationJson),
	true,
};



HTTP:PostAsync(
	'http://localhost:9999',
	table.unpack(t),
	{
		['Request-Type'] = 'Status'
	}
); ---> Throws: Unable to cast Dictionary to HttpContentType.

HTTP:PostAsync(
	'http://localhost:9999',
	t[1], 
	t[2], 
	t[3],
	{
		['Request-Type'] = 'Status'
	}
); ---> OK.

Expected behavior

Both calls to :PostAsync() should work.

This is how returning multiple values works in Lua.

I find that to be so inconvenient…

[Yuria_theWitch]

While the semantics of multiple return in Luau are indeed surprising at times, they are inherited from Lua and we cannot change them without breaking backwards compatibility for all existing code.
