[PD-dev] the future of [declare] and canvas_savedeclarationsto()

[Hans-Christoph Steiner]

I think this issue is pretty clear, and the languages that I know  
would fall along the lines of "each patch/abstraction has its own  
namespace" or in other words "#include only affects the one .c  
file",  "import only affects the one .py file", etc.  So I agree with  
Frank.  Global settings are global, and canvas-local settings are  
local to the original file.

The "semi-functional" part is the full paths that Marius mentioned.

Then the other question is how to use something like "#X declare"/ 
canvas_savedeclarationsto() in externals.  I'd like to create an  
[import] modelled after Python's import does, so I'd like to use "#X  
declare"/canvas_savedeclarationsto() with it.
