In complex projects, there might be several library copies (with the
same or different versions). As there is no way to build a reliable
dependency graph between libraries, a project library depends on all
other libraries. As a result, there might be several declarations in the
classpath with the same name and signature.
Normally, K2 issues a 'resolution ambiguity' error on calls to such
libraries. It is acceptable for resolution, as resolution errors are
never shown in the library code. However, the backend, to which
'evaluate expression' needs to pass FIR afterwards, is not designed for
compiling ambiguous (and non-completed) calls.
