MyGlobalNumber = 10
MyEnum = enum{
"a=1"
"b"
"c=MyGlobalNumber"
"d"
"e=100"
"f"
"g=2^3"
"h"
"i=math.floor(100.001)+MyGlobalNumber*10-100/5"
"j"
}

更正：有個地方多余了
tmp = "return " .. string.gsub(val,"([%w_]+)",function (x) return enumtable[x] and enumtable[x] or (type(_G[x]) == "numbers" and _G[x] or x) end)
改成：
tmp = "return " .. string.gsub(val,"([%w_]+)",function (x) return enumtable[x] and enumtable[x] or x end)
