@zeux omg yes. It infuriations me that for some reason #if is put on column 0. Makes no bloody sense

@forrestthewoods @zeux I assume it's because #if can blow through any sort of scope rules etc. Except that usually we don't write it so it does...

@TomF @forrestthewoods @zeux iirc there used to be a rule that the # had to be on column 0 but the rest of the directive could be indented? So you could write stuff like

# if (FOO)  
# define BAR  
# endif  

No one enforces that anymore (you can indent the # now), but I wonder what was the origin of that rule

@reedbeta @TomF @forrestthewoods @zeux some very early cpp's assumed that, but having blank characters before the # has been legal since C89. So you're on pretty safe ground :)

@andrewwillmott @reedbeta @TomF @zeux C89? Better wait until 2029 just to be safe!
