error with table.serialize(environment)

error with table.serialize(environment)

[Peter Münster]

Hello,

Here a test file "test.cld" to show the problem:

local t = {bla = "blub"}

-- no problem:
print(table.serialize(t))

-- error: l-table.lua:565: unable to dump given function:
print(table.serialize(environment))

context.bye()

-- 
           Peter

And what about replacing line 565 by something like this:

        handle(format("%s [%q]=loadstring(%q),",depth,k,
                      debug.getinfo(v).what == "C" and "C code" or dump(v)))

local function dummy() end

local f = getinfo(v).what == "C" and dump(dummy) or dump(v)

handle(format("%s [%q]=loadstring(%q),",depth,k,f))

(and some more places)

or

local f = getinfo(v).what == "C" and dump(function(...) return v(...) 
end) or dump(v)

not that it makes much sense to dump functions
