I wrote a weird bug the other day.  I had a function that returned a 
4-tuple and wanted to unpack it, so I wrote:

    var1,
    var2,
    var3,
    var4 = my_function()

which isn't a syntax error, but also isn't what I meant.  Depending on 
whether var[123] have pre-existing values, this doesn't even produce a 
run-time error.  Emacs encouraged me in this crime by merrily 
auto-indenting the code the way I expected :-)
