Fuck me with a spoon.

Why the hell cannot people see that "equivalent" and "same" are two 
totally different meanings.

.. and this is relevant how? They are different strings. Not the same.

Equivalence doesn't matter. Equivalence is *evil*. Equivalence is what 
gives us case-insensitive filesystems ("because the names are 
equivalent").

Filesystems don't *want* equivalence. They want a much stronger exactness 
guarantee. Exactly because sometimes the differences matter.
