+# Summary
+
+Allow a re-export of a function as entry point `main`.
+
+# Motivation
+
+Functions and re-exports of functions usually behave the same way, but they do
+not for the program entry point `main`. This RFC aims to fix this inconsistency.
+
+The above mentioned inconsistency means that e.g. you currently cannot use a
+library's exported function as your main function.
+
+# Detailed design
+
+Use the symbol `main at the top-level of a crate that is compiled as a program
+(`--crate-type=bin`) – instead of explicitly only accepting directly-defined
+functions, also allow re-exports.
+
+# Drawbacks
+
+None.
+
+# Alternatives
+
+None.
+
+# Unresolved questions
+
+None.
