Pigment {checker texture{...} texture{...}} doesn't work... any ways to
fix it? or checker only works
for colors?

How about a comma between the two texture entries?

You can't use texture statements inside a pigment statement.

texture { checker
           texture {...}
           texture {...}
}

Yes you can. This works:

sphere 
{ 0, 5
  texture { checker texture { T_Wood1 }, texture { T_Wood2 } }
}

It also works if you replace the texture identifies with texture
declarations. It even works with the comma left out even though
technically it should parse it as a two-layer texture and a void
texture (i.e. the second entry in the checker pattern should default
to whatever it defaults for textures)

Your missing the point, Peter. The original posters example was:

pigment {checker texture{...} texture{...}}

You said to add a comma. It just won't work because he is trying to
use textures in a pigment statement. I was right when I said you
were wrong :)

I admit. Guilty. Please have mercy oh mighty Ken. How dare I doubt
your knowledge! :)

Upon a second look I see why I missed that pigment word the first
time. It's capitalized. My POV-keyword-only filter must have rejected
it.

You can use textures inside a texture statement like the one example
that Peter provided.

This IS OK - texture { checker texture{...} texture{....} }

You cannot use textures inside a pigments statement like the example
you provided.

This is NOT OK - pigment { checker texture{....} texture{....} }

 If you need to use different pigment patterns inside a pigment statement
you could do it like this this example illustrates -


#declare Pig1 = pigment{checker color rgb 0 color rgb 1}
#declare Pig2 = pigment{hexagon color red 1 color green 1 color blue 1}

box { -1,1
           pigment { checker
                     pigment { Pig1 scale .5 }
                     pigment { Pig2 rotate 90*x scale .5 }
                   }
    }
