Is there a way to extract the "original" string from variable_value? By 
this I mean the one taken from command line or ini file before 
conversion to int, float etc...? I suppose for vectors this would be 
impossible - you would need a vector of "original" strings. But this 
would at least cut the cases down. Is it possible to as a variable it 
holds a single or multiple values?

Thanks,
