in reply to Perl print statement + HTTP request

What you are thinking of is some kind of a closure, like this:

my $make_output = sub { my ($Registration, $Rank) = @_; return @{ $Data{$Registration}->{Name} }[$Rank], "\t"; }; print $make_output->($Registration1, $Rank1), $make_output->($Registration2, $Rank2);

Though I guess that you might be able to simplify your code by using techniques such as OO.

Update: The following code shows what an OO variant would look like. Maybe you are trying to do something completely different; but according to your short line of code, I imagine that you could probably use this example.

my $data = Data->new( ... ); print $data->make_output($Registration1, $Rank1), $data->make_output($Registration2, $Rank2); # class definition package Data; sub new { # set up data object # ... } sub make_output { my ($self, $Registration, $Rank) = @_; return @{ $self->{$Registration}->{Name} }[$Rank], "\t"; }

    Exactly what i was looking for and a straighforward method. Anyone have any idea about the HTTP request part? For me it seems it would not matter but I want to make sure.

[Corion]: Meh. I think I have now the parts down that I want from a simple Javascript frontend for single-page- applications with a aPerl backend. But it seems that all Javascript templating modules either don't support two-way binding (which would be nice) or ...
[Corion]: ... don't support server-side precompilation (which means the client has to compile all templates to Javascript themselves), or are giant frameworks that expect to do everything (which is not what I want)
[Corion]: I feel that there is a talk somewhere in there, either about the structure and parts, or how I used several parts to get a complete whole.
[Corion]: Maybe I can still find something that is compatible with handlebars.js (which has JS precompilation) but allows for two-way data binding (which is great for the UI)
