Place this code in your table or autorun folder, and you'll be able to access lua variables as if they're symbolhandler symbols

Code:

if luasymbols then
  unregisterSymbolLookupCallback(luasymbols)
  luasymbols=nil
end
luasymbols=registerSymbolLookupCallback(function(str)
  return tonumber(_G[str])
end, slFailure)


I'm sure you can upgrade this more to add in function calls and what not (tip: use slNotSymbol to get multiple 'possibilities')

another version that will let you execute lua code in case symbol lookup fails:
Code:

if luasymbols then
  unregisterSymbolLookupCallback(r)
  luasymbols=nil
end
luasymbols=registerSymbolLookupCallback(function(str)
  local c='return '..str
  local lc=loadstring(c)
  if lc then
    return lc()
  end
end, slNotSymbol)


you can then go to address
Code:

getAddress('00500000')+1000

and it'll resolve
