I'm still thinking about the difference between "< <(...)" and "<<<

Not sure about the extra “<”, but “<(«cmd»)” gets substituted with the
name of a file (i.e. not stdin) that the process can open and read to get
the output of «cmd». Similarly “>(«cmd»)” gets substituted with the name
of a file (i.e. not stdout) that the process can open and write to feed
input to waiting «cmd».

“<<” and “<<<”, on the other hand, are for specifying alternative sources
of inline data for stdin, or you can use “«fd»<<” and “«fd»<<<” to specify
an alternative «fd» that the process will expect to find already open for
reading, to obtain that data.
