That would be more succinctly be expressed as

  ((equal? sp-id es-id)

In which case it should work equally well in the old and the new
LilyPond versions.  Assuming I counted the parens right.

Finish my sentence at the end of the paragraph:

... No spanners are drawn at all in this example.

Hello list,

to my grief I noticed that David Nalesnik's id-aware spanner
implementation in scheme no longer works in 2.39.48. It gives me errors
like "warning: No spanner to end!!" and "warning: incomplete spanner
removed!" if there are overlapping spanners. No

For reference, I again attach David N's (most recent) textspanner
implementation. The \score block is a minimal example.

Note: this worked fine with 2.19.39, and fails with 2.19.48. I didn't
look at intermediate versions.
