Hi
I already added MAC-address lexem and shortened minimum bytestring length
to 9 bytes in EVPN branch (to represent 10-byte ESI) :

I was afraid to shorten non-colon variant, becuase somebody using the variable name "feedfacecafebeef01" might get hurt. :)
So i would keep it at that limit and used e.g. hex:XX:YY:... syntax
for shorter ones.
But Maria has a good point, that it may be beneficial to be able to input the blob with spaces or even line breaks, which requires some sort of "brackets".
