Make first(g) more efficient: extract only 1 value
first(g) was extracting two values, which, if g is slow, made first(g)
slow. And if the second extraction were to throw an error, then
first(g) would throw that error, which is clearly not the right thing to
do. Besides that, first(g) was allocating garbage, which it no longer
does.
