Anyway, my indirect point was that AppleScript ought to be able to

POSIX file "~/Desktop/some.txt"

I'd point out that other scripting languages, even ones that grew
up on Unix, do not support that, and they don't support it because
"~" isn't actually part of POSIX path syntax.
But Chris,
I'd didn't say it was part of POSIX path syntax (as in POSIX
standard). What I said was: "…AppleScript ought to be able to do
tilde expansion on a POSIX file cast.".
Meaning that the aim of the facility shouldn't put the onus on the
user to figure out whether or not that "~/xxx", which is a widely
used convention in OS X, is eligible. Rather, it should make a
reasonable attempt to convert whatever into a usable 'file'.
Even better would be for AppleScript to up the ante a bit on the Tcl
approach with something like:
native path of "~/xxx/some.txt" using YYY conventions
where YYY would currently be one of POSIX, HFS, DOS, URL, or
(something I haven't thought of right now). If YYY is omitted, it
would mean whatever convention is valid for the platform AppleScript
is currently running on. So:
native path of "~/xxx/some.txt" using URL conventions
--> "file://localhost/Users/me/xxx/some.txt"
native path of "~/xxx/some.txt"
--> "/Users/me/xxx/some.txt"
native path of "~/xxx/some.txt" using HFS conventions
--> "~:xxx:some.txt"
