So my question is: Is it possible for me to use the "-E" switch in
the perl debugger/interpreter to automatically invoke the "say" feature,
or can that only be used with perl one-liners (that is, scripts written
entirely at the command line)?
The reason lies in toke.c: the debugger is loaded before -E is processed:
if (PL_perldb) {
/* Generate a string of Perl code to load the debugger.
[...]
if (PL_minus_E)
sv_catpvs(PL_linestr,
"use feature ':5." STRINGIFY(PERL_VERSION) "';");
So at the moment, the answer is no. I'll ask P5P whether it has to stay
this way.
