The convention in manual pages is that optional arguments are denoted with brackets. My expections from just the above synopsis would be precisely the old behaviour (which the test suite apparently relies on): FILE is optional and STDIN is used if FILE is not supplied. > So it seems that XML::Parser's parsefile was able to handle '-' with > the 2-args-open() and fails to do so with the 3-args-open().
