Ah, sorry, I missed that thing about escaping the tab.

See
:help expr-string
:help literal-string

Within single quotes, every character is taken literally, even a
backslash, except that two single quotes mean one.

You should have used double quotes with backslash-escaping, like this
(referring to your original post):

exec 'e' a:dir . "/\t"
or
execute 'e ' . a.dir . "/\<Tab>"

HTH,
Tony.

THE LESSER-KNOWN PROGRAMMING LANGUAGES #13: SLOBOL

SLOBOL is best known for the speed, or lack of it, of its compiler.
Although many compilers allow you to take a coffee break while they
compile, SLOBOL compilers allow you to travel to Bolivia to pick the
coffee. Forty-three programmers are known to have died of boredom
sitting at their terminals while waiting for a SLOBOL program to
compile. Weary SLOBOL programmers often turn to a related (but
infinitely faster) language, COCAINE.
