Idea: Context sensitive attribute functions.

[12345swordy]

Pseudocode:
void example()
{
static if(Context = @nogc)
{
//nogc implementation
}
else
{
//gc implementation
}
}

This is useful as it eliminate the need to create multiple 
functions for each possible system attribute hence reducing 
redundant code. There are advantages of having a gc/unsafe/throw 
code. Why not use them if given the opportunity based on its 
context?
