Amazon's CodeWhisperer

There has been a fair amount of concern recently about Microsoft's Copilot
system, which many see as possibly putting its users in violation of free-software
licenses. But, naturally, Copilot is not the only offering of this type;
Amazon has put out a preview version of 'CodeWhisperer', which is
also a machine-learning-based coding tool that was trained on (unspecified)
open-source code. From the FAQ:

CodeWhisperer’s reference tracker detects whether a code
recommendation may be similar to particular CodeWhisperer training
data, and can provide those references to you. This allows you to
easily find and review that reference code and how it is used in
the context of another project.
