in thread Perl Program - Out of memory?

You have "foreach" loops 10 deep in that program. If each one runs only 3 times, that's 60,000 iterations of the inner loop. I would seriously consider rethinking what you're trying to do, or how you're doing it, because an O(n^10) algorithm is usually a recipe for disaster.

[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)
