Steps to replicate the issue (include links if applicable):

• Please see this example
• and the failing test cases (like Z32804) on monolingual text from string, composition (Z27080)
• The general failure of string identity, Composition: Abstract (Z32142) may be related.

What happens?:
Evaluated results contain argument references (or, in the third case, evaluation fails).

What should have happened instead?:
The argument references should have been resolved, so that the evaluated results are proper objects.

Software version (on Special:Version page; skip for WMF-hosted wikis like Wikipedia):

Other information (browser name/version, screenshots, etc.):

Raised here. Please note the disconnection, which has an adverse effect on performance, because the alternative implementations are in JavaScript and Python.

I think Z30651 has the same form as Z32142, the only difference being the argument reference in the latter case.
