This is fine: `if (open(my $fh, '<', $qfn)) { ...read from $fh... } # $fh is out of reach here` [download] Perl doesn't care where the `my` is to the point that it allows the following (even though the behaviour is officially undefined): `my $fh if ...;` [download]	[reply] [d/l] [select]

that's another thing: `if(my $x = expr) { ... } # my always executed my $x if expr; # my is conditional if(expr) { my $x } # as above` [download] 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 Oha	[reply] [d/l]

"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` [download]	[reply] [d/l]
