pop_to_tag		pop elements from stack, until pop a tag.
values_shift_to_1		[end by a tag] make sure there has only one value.	a,b = (func()), 2;-- make sure b equals to 2	(1) (2)
local		declare variable(s) in current environment, and init them to default values(nil).	local foo; local a, b;
local_init		declare variable(s) in current environment, and init them to specify values.	local a, b = 1, 2, 3
table_get		used to access key-value of one specify table	tab["key1"] tab[1 + 2] tab[func()]
table_get_imm	identifier	used to access key-value of one specify table by immediate string	tab.name tab.socket.port tab._test func().key
table_set_tkt			tab['key'] ='value';
assign add_assign sub_assign mul_assign div_assign		a = b; a += b; a -= b;
add		sub, mul, div, and, or, less, greater, less_eql, greater_eql, eql_eql, not_eql are the same.	1 + 2
call		call a luax object	func() func(a, b) tab[1]() func()()
