[P4-dev] Strict ordering of options required to be specified for P4 parser ?

In IPv4/IPv6 or TCP packets, options can appear in any order in the packet.
However, can P4 handle this generically without any limitations ? The TLV
example that I looked seems to be using a pragma to specify the option
ordering and it was mentioned in the documents somewhere that we can't have
circular dependencies in the parser tree. Can the experts please comment ?
