WebDec 19, 2015 · Because a PMT vector is pretty much like a python list: It can contain any combination of PMT types, for example: v = pmt.to_pmt ( ["This is a string", 42, complex (0,-1)]) is perfectly valid, but can't be a uniform vector. Because the input type->output type mapping should be consistent, I consider converting a python list to a PMT vector the ...
