Description

It seems that we have an ability to have named dependecies like (deps (:first-dep foo.cppo.ml) <other files that foo.ml includes>). Could we also have named targets? Or at least a variable that expands to first target (like in Makefile)?

Contributor guide

Research direction
Study how dune currently expands variables in dependency declarations (e.g., `(:first dep ...)`). Investigate the representation of targets within dune's internal model. Compare with Make's automatic variables like `$@` and `$<`. Propose syntax for named targets or a built in variable for the current target's name. Look at existing issues or discussions about variable expansion.
