Alter default behavior of 'cond' parameter in dado:select

[rousbound]

function M.select (self, columns, tabname, cond, extra, mode)
	if type(cond) == "table" then cond = sql.AND(cond) end -- <<<
	local stmt = sql.select (columns, tabname, cond, extra)
	local cur = self:assertexec (stmt)
	local tm = type (mode)
	local t
	local _mode = mode
	if tm == "table" then
		t = mode
		_mode = 'a'
	end
	return function ()
		-- This table must be created inside this function or it could
		-- make `selectall' to return the same row every time.
		if tm == "string" then
			t = {}
		end
		return cur:fetch (t, _mode)
	end, cur
end

Would it be desirable to have this shortcut to cut out some characters while writing dado functions?

So we could get this:

local usuario = conn:select( "*", "user", { id_user = id_user }, "order by name", "a" )

Instead of:

local usuario = conn:select( "*", "user", sql.AND{ id_user = id_user }, "order by name", "a" )
