- The compiler now shows a specific syntax error when trying to use an
151

angle-bracket syntax for generic types or function definitions:

error: Syntax error

If you were trying to define a generic function, Gleam does not use angle brackets.
161
+
Instead, you should write types in the parameter list with lower-case names.
162
+
Each unique lower-case name becomes a type variable:
163
+
164
+
fn example(arg: t) -> t
165
+
166
+
See: https://tour.gleam.run/functions/generic-functions/
