Re: [boost] Interest in a small array count facility?

When you write something like, for instance,

COUNT_OF_N(3, x)

though, it's not enough to check that x is an array. It shall be an array, x[0] shall be an array, x[1] and x[2] shall be arrays. I can imagine implementing it with some pp-lib iteration which automatically generates

sizeof(x[0])/sizeof(x[0][0]) sizeof(x[0][0])/sizeof(x[0][0][0]) sizeof(x[0][0][0])/sizeof(x[0][0][0][0])

up to a given limit,

So what's wrong with that?

but I'm not sure it can *reliably* be done with templates only.

You need a macro anyway, don't you? -- Dave Abrahams Boost Consulting www.boost-consulting.com
