Description

[range.utility.conv.to]:

It seems like:

If C does not satisfy input_range or convertible_to<range_reference_t<R>, range_value_t<C>> is true:

can be replaced with:

If C does not satisfy input_range or R satisfy container-compatible-range<range_value_t<C>>:

But it doesn't seem necessary.

Research direction

Read the [range.utility.conv.to] wording and compare its constraint with the definition of container-compatible-range in the linked C++ standard clauses. Review the four existing comments for the rationale, then determine whether the proposed substitution is needed and update the draft wording only if the discussion supports a clear resolution.
