Hi Federico,

the usage of pseudo-variables inside the regexp was avoided due 
performance reasons - all regexp are compiled at startup, they being 
only evaluated on runtime.
By having variables into regexp, the compilation of the expression will 
must be done each time at runtime :(.

there is only one attempt in this direction - it might help you ; see 
the fm operator in avp_check :
