Executable has executable file type for a reason - it 
self-implies that the main function of the file - is to be 
executed.
The problem with making source code files executable is that, 
source code files, might not always be monolithic executable 
code, but a part of a bigger interconnected program.
That would lead to partily working program execution, and most of 
the times guess work of whether source code file was supposed to 
be executed.

The clear alternative would be: .exe file on which, if 
rightclicked - would open context menu showing posibility of 
"edit/improve this executable". Which would not create additional 
problem mentioned above.
