BGP path is a list of autonomous system numbers. You can't write literals of this type.
There are several special operators on bgppaths:
<cf><m/P/.first</cf> returns the first ASN (the neighbor ASN) in path <m/P/.
<cf><m/P/.last</cf> returns the last ASN (the source ASN) in path <m/P/.
Both <cf/first/ and <cf/last/ return zero if there is no appropriate ASN,
for example if the path contains an AS set element as the first (or the last) part.
<cf><m/P/.len</cf> returns the length of path <m/P/.
<cf>prepend(<m/P/,<m/A/)</cf> prepends ASN <m/A/ to path <m/P/ and returns the result.
