Friendly-C

[bearophile via Digitalmars-d]

Found through Reddit. A nice incomplete list that specifies a 
"friendly C" that replaces many occurrences of "X has undefined 
behavior" with "X results in an unspecified value":

But I agree with one comment:

memcpy and memmove ought to remain distinct, but I think that an 
overlapping memcpy ought to result in unspecified garbage being 
written rather than undefined behavior.<
