Remarks

a huge number of different Weaving Pattern instances will be created, as result of implementing render functionality by delegating to some external media processing library. Each time, a highly optimised and tailored instance of Turnout::weave() is generated. However, by all means we must avoid generating additional repetitive generic code, which is only used occasionally and for unit-testing. Rather, with the help of this »backdoor«, diagnostic code can exploit the similar basic layout of weaving pattern templates to gain access to some common infrastructure, notably the predecessor ports.
