For filtering of named variants is used character ">" because there was
problem with conflict with = in expression key = value. The char ">"
could be changed to something better but it should be different from "="
for optimization of speed.
Additionally named variant adds keys to final dictionary in case of
example is it (virt_system = linux). It should reduce size of config file.
Keys defined in config and keys defined by named variants are in same
name space.
