anyTuple

Detect whether a generic tuple A contains an element satisfying the predicate pred.

template anyTuple (

alias pred

A...

) {

alias predTemplate = unaryPred!pred;

static if(A.length == 0)

static if(!(A.length == 0))

static if(!predTemplate!(A[0]))

static if(!(A.length == 0))

static if(!(!predTemplate!(A[0])))

}
