We have an "AppPath" expression, and it's really useful for loading external files.
I propose a "Bin" expression for loading files stored as resources. Any files, whatever they may be (as long as it's a file that some object or construct itself can open).
The idea came to me when I was thinking about the .mesh files exported by the mesh editor. I thought it may be possible to do a sort of frame-by-frame animation on a mesh by loading a series of .mesh files. I thought storing the .mesh files into the binary might be nice, but then there'd have to be a "Load mesh from resource" action, etc. Then it occurred to me that if you were allow the loading of files from binary, you'd have to add the "Load file from resource" action to all objects for whatever other file types, and that wouldn't really be necessary if you had a more general "Bin" type expression.
It would also be useful for text files, .ini files, hell... even .jpgs or whatever else. Wherever you have to load a file, just use
Of course, this feature would have to come after the capability to use resources for more than just sounds.
