| Maybe, but Posix says this isn't a variable assignment context, as POSIX
| defines variable assignments, and technically the shell shouldn't perform
| tilde expansions after `=' or `:' at all. You could argue that bash has a
| bug here in that it expands the tilde after the `='.
It may also be that this is a bug in POSIX, as all ksh shells seem to
act the way that bash does, expanding the first ~ but not the secpod.
Most other shells expand neither, except the NetBSD shell which treats
this as a var assignment (which it is really, however explained away in
POSIX) and expands both.
It is likely that if someone were to file a posix bug report about this,
it would turn into "unspecified" whether ~ expansion is done in that context.
