I naively thought that it is enough to check permission to write
(create) in top directory, like e.g. ~/usr (I assume that this directory
exists) or `~', if to talk about `~/usr/local/...'. Is this perl
limitation, e.g. missing analog of `-p' parameter of `mkdir' or
something other? I'm just curious.

Correct me if I wrong, installer will work with
  /this/is/path/to/TL/installation
path only if path
  /this/is/path/to/TL
already exists and writeable by user, i.e. it will create only last
component of (full) path?

Yes, I agreed.
