Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I thought this would work
#!/usr/bin/perl -- BEGIN { package OOO; sub new { my( $pkg, $path ) = @_; bless \$path, $pkg; } sub filetest { warn "its fake @_\n"; 'fake' } use overload '-X' => \&filetest; $INC{'OOO.pm'} = __FILE__; } use strict; use warnings; use OOO; -f OOO->new('.'); __END__ Operation """": no method found, argument in overloaded package OOO at + - line 6.

I don't understand, what did I miss?

    A Super Search on “Operation """"” finds this 2009 thread: overload op requires stringify overload ?? Applying Bloodnok’s “fix of sorts” —

    #! perl -- BEGIN { package OOO; sub new { my( $pkg, $path ) = @_; bless \$path, $pkg; } sub filetest { warn "its fake @_\n"; 'fake' } use overload '-X' => \&filetest, fallback => 1; $INC{'OOO.pm'} = __FILE__; } use strict; use warnings; use OOO; -f OOO->new('.');

    gives:

    22:15 >perl 804_SoPW.pl its fake OOO=SCALAR(0x1c15434) f 22:19 >

    Is that what you were wanting?

    Anyway, hope it helps,
