Default variant is not being transpiled properly

[germanftorres]

Hi,

I'm trying to use this compiler in my build process. With the demo ftl source in README.md, when trying to display the sync-dialog-title (which references another key), I get an exception ($.capitalization, can't access property capitalization of undefined). Seeing the generated ouput I feel that maybe in sync-dialog-title the call to value() should be value({}) so that the call does not throw, but not really sure.

Anyway great work, I would guess that messageformat is a more established tool, but fluent also looks promising as long as we can rely on build time tools like this one.

Thanks!

    Hi how are you!!

Just calling.value({}) doesn't seem to really solve the issue here apart of silencing the error. How one could pass the correct capitalization value (uppercase/lowercase in this example) if the value used is always an empty object?

I'll dig a bit more into the compiler code to see if I can shed some light in this issue as well understand more how the compiled code with selectors is supposed to be used/generated.

Is this related to this comment on one of the tests for select expressions?

I'm trying to figure it out how to avoid the undefined reference without breaking any API
