You've been using Perl for a year and this is your first rude shock?
As one of my favourite professors says about Perl:

"Maybe I'm corrupted by normal language syntax."[1]

Now, about how I typically do interactive stuff in Perl:

print "Enter some value: ";
chomp( $answer = <STDIN> );

The chomp() bites off the newline at the end of the input. Of course,
you might want it, so if you do, do not chomp(), just say:

$answer = <STDIN>;

And of course, since it is Perl, it allows extreme laziness:

$answer = <>;

Hope I answered your question.
