This would mean that in a statement like
    self.write(PERSID + str(pid) + '\n')
the write function should perform the parsing of the expression
"PERSID + str(pid) + '\n'", while for me it's obvious that it only
gets its result and can't recover the spelling of the expression
used to compute it.

It's similar for commandline arguments. The list of files doesn't need
to be written explicitly: it can come from expanding variables, from
globbing patterns, from substitution of output of some other command,
from arithmetic computation etc. You can't expect applications to do
all this. This is the job of whoever calls your program to generate
arguments, e.g. the shell. The user just tells the shell how to
generate them using the shell's language, which includes variables,
wildcards etc.
