Re^2: and multiple statements

But an if would be clearer.

Is it? Always? For everyone?

Considering the idom open ... or die ... is quite common, I'd say that

open ... or do {...;...}
[download]

is clearer than

if (!open ...) {
    ...;
    ...
}
[download]

I'd certainly write the former.

It's quite common because it's required in the case of `open(my $fh, ...)`, not because it's clearer.	[reply] [d/l]

Required? I don't follow. `if (!open my $fh, "<", "filename") { warn "Whatever"; return; }` [download] is perfectly valid code. There's no requirement that that is to be written as `open my $fh, "<", "filename" or do {warn "Whatever"; return;};` [download]	[reply] [d/l] [select]

Perfectly valid code, but perfectly useless because you can't use the file handle you just opened. You'd have to move the rest of the code into the `else` body.	[reply] [d/l]
