Currently scripts are uploaded in text file form only. However, for larger projects, it would be much better to be able to compile code into an assembly and upload the compiled assembly instead of putting all my code in one giant script file.
Also I should be able to upload multiple assemblies and reference one assembly from another. I should also be able to reference an assembly from a simple file-based script too.
I would of course expect Sansar to scan the assemblies for references to not allowed APIs.
