+Having an invalid package dependency that looks like an opam-versioned package
+gives a good user message rather. It is very likely that users will type
+foo.1.2.3 for a package version due to the convention in opam.
+In this case we could also hint at the correct syntax for dune-project files.

+  Error: "foo.1.2.3" is an invalid package dependency.
+  Package names can contain letters, numbers, '-', '_' and '+', and need to
+  contain at least a letter.
+  Hint: (foo (= 1.2.3)) would be a correct package dependency
