This code under strict gets an error on the line local numRanges: number = #ranges saying that boolean can't be converted to number

local function TestFunc(ranges: {number}): {number}
    if true then
        ranges = {} :: {number}
    end
    local numRanges: number = #ranges
    return ranges
end

Thanks for the report. This should be fixed in the 644 release. Cheers! 😸
