“static const” vs “#define” vs “enum”
...sion for static arrays at function scope; both (2) and (3) can.
Under C99, all of these can be used for local arrays. Technically, using (1) would imply the use of a VLA (variable-length array), though the dimension referenced by 'var' would of course be fixed at size 5.

Using sections in Editor/Display templates
I want to keep all of my JavaScript code in one section; just before the closing body tag in my master layout page and just wondering the best to go about it, MVC style.

P.P.S. You also need [forward rel...

class PairSequence:
