Re: My first module

Because $in_arg is scalar my $in_arg=@_; assigns the number of elements in @_ (1) to $in_arg.

Instead either:

my ($in_arg)=@_;

or:

my $in_arg=shift;

Because `$in_arg` is `scalar my $in_arg=@_;` I would say, if I really wanted to say that, `my $in_arg=scalar @_;` [download] but then I would just say that `@array` evaluated in scalar context returns the number of elements in `@array` and that assignment to a scalar imposes scalar context. Or something like that... Update: since this was downvoted, why don't you actually try? `$ perl -e 'scalar my $in_arg=@_' Can't modify scalar in scalar assignment at -e line 1, at EOF Execution of -e aborted due to compilation errors.` [download] Update2: I read Re: My first module once again and now I realize I read it uncorrectly. I use a theme in which occasionally inline code is not visually distinctive enough, and GrandFather didn't put a suitable interpunction sign, so this added to my confusion and misreading. Sorry, my apologies...	[reply] [d/l] [select]
