Subject: blocks: remove unnecessary call to pmt::intern at runtime
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
typical usage:
message_port_pub(pmt::mp("out_port"), …)
which is bad, as it implies hashing of a string, allocation of memory,
deallocation, finding the hashed string in the table of interned strings
and returning a unique pointer (which for reasons of PMT awesomeness
isn't even unique) to the interned port name.
Replacing all these port name ad hoc ::mp() calls by reusing one,
private, port name member.
