It appears that len() is broken in versions 65 and later:
0>> len(x)
1
// Time 0
1>> len(x,y)
1
// Time 0
2>> len(x,y,z)
3
// Time 0

So something is wrong with len(x,y)

It's a side-effect of the changes I made to find the memory size of objects for devices with a (very) small amount of RAM. I will disable it. I'll keep only size() for diagnostics.

Fixed in 1.5.0-69.
