[Templates] listifying "scalars"

[Jess Robinson]

Hi folks,

The 2.15 has an enhancement whereby using .list on a "scalar" should turn 
it into a list. I quote the word "scalar", because it appears to really 
mean "simple scalar", i.e. not references, or blessed refs. The docs 
should probably reflect this.

Anyway, that leaves me with a problem. My sub returns a list of blessed 
objects, except that when there's only one, TT conveniently de-listifies 
the result, however since I'd like to access it as a list anyway, I used 
.list on it, which conveniently turns it into a list of hashrefs with 
values and keys.. i.e. treats it as a hashref. Code that worked in 2.14, 
in the SQL::Translator test suite i.e.:

[% table.pkey_fields.join(", ") %]

Now fails to work in 2.15, when the result of pkey_fields is a single 
object.. Adding .list does not fix this.

Any ideas how to fix this backwards compat problem, or how to make the 
test suite work with lists of blessed scalars?
