I have introduced the first two errors in the reduction process. 
The third is the one that triggers a crash of my DMD version. I 
am keeping my compiler updated, I have compiled it yesterday, and 
it crashes after giving the error:

test.d(28): Error: cannot modify const expression s

Now I don't know if it's a problem of just my compiler, or if 
it's a normal compiler bug.
