Ah. TT2 is broken in that regard, I'm afraid. My bad.
There's a workaround for TT2 in the form of the scalar plugin. That's
new to 2.20 (which isn't released yet), but you can grab it from SVN.
[% USE Scalar %]
# TT2 calls object methods in array context by default
[% object.method %]
# force it to use scalar context
[% object.scalar.method %]
# also works with subroutine references
[% scalar.my_sub_ref %]
The problem is fixed properly for TT3. All methods will be called in scalar
context by default. The '@' sigil will be used to force list context when
you really want it.
[% object.method %] # scalar context by default
[% object. at method %] # force list context
