I just did some searching in the GNAT sources.  About a million lines
of code.  About 7000 slices.  About 1500 slices on the left of ":=".

Warning: this is a crude search -- I probably have both false
positives and false negatives.

I must admit, these are higher numbers than I expected.

Almost all of them look like strings, at a quick glance.

OK, but I'm not comparing them to other languages.  I'm comparing them to
other features of Ada (or other features that I'd like to see
in Ada).
