It eventuated in Go, which is definitely aloft, and responds
to Mike Bianchi's specific desires. Go also has a library
ecosystem, which C does not.

With its clean parallelism, Go may be suitable for handling
the complexity of whole-paragraph typsetting in the face
of unexpected traps, line-length changes, etc.
