function in "luaproc.newproc( function f ) " requires luaproc require

[maxguru]

Works:

local luaproc = require("luaproc")
local x = function()
    local luaproc = require("luaproc")
    print( luaproc.receive( "achannel" ))
end
luaproc.newproc(x)

Doesn't work:

local luaproc = require("luaproc")
local x = function()
    print( luaproc.receive( "achannel" ))
end
luaproc.newproc(x)

On the other hand, this works without require in the newproc block,

local luaproc = require("luaproc")
luaproc.newproc( [[
    print(luaproc.receive("achannel"))
]] )

My skills are rusty, but I'm pretty sure that the nested function x can capture an upvalue only if the upvalue is a string, boolean, number, or nil. It can't capture a function.
