unless only passed one function.

Of course, this doesn't make sense for any but the innermost function, e.g.

int f(int){..} 
int g(int){..}
int h(int,int,int){...}

alias compose!(f,g,h) F;
assert(F(x,y,z) == f(g(h(x,y,z))));

This functionality can be trivially added by changing in composeImpl

doIt(E)(E a)

to 

doIt(E...)(E a)

If conserving param modifiers is desired, it would likely take a good deal more
work.
