in reply to Re^3: if(my) scope
in thread if(my) scope

that's another thing:
if(my $x = expr) { ... } # my always executed my $x if expr; # my is conditional if(expr) { my $x } # as above
what i was saying is that if i can my on a arg of a function, maybe i can do the same in the "argument" of a if

    "as above" is unclear. I think you meant "my is conditional", but it's really "my always executed" (in the scope in which it resides).
    c() or my $x; # XXX Conditionally executed c() and my $x; # XXX Conditionally executed my $x if c(); # XXX Conditionally executed (same as previous) sub foo { my $x } # OK Always executed if (c()) { my $x } # OK Always executed die; my $x; # OK Always executed
