while compiling (  with -std=gnu++20 ) , over and over while building, this
warning comes up:

./liboctave/array/Range.h: In lambda function:
./liboctave/array/Range.h:276:22: warning: implicit capture of 'this' via
'[=]' is deprecated in C++20 [-Wdeprecated]
  276 |         idx.loop (n, [=, &array] (octave_idx_type i)
      |                      ^
./liboctave/array/Range.h:276:22: note: add explicit 'this' or '*this'
capture

https://isocpp.org/files/papers/p0806r2.html suggests that 'this' should
explicitly be invoked here (though none of the examples have a second
argument)

and, granted, the easy way to make this go away is to just not bother with
-std=gnu++20 but still: use of deprecated C++ is a flaw whether it's valid or
not.
