right, it was just convenient for the rfc ;-)

but I wonder we could keep it that way anyway and have:

current way of using pre-defined metrics:
  # perf stat -M m1,m2,m3

simple/fast way of checking on metric:
  # perf stat -m 'm4=....'

metric from user file:
  # perf stat -M m5,m6 --metric-file=path

thanks,
