Compile error when defining * operator in scala 3 extension methods

[ajrnz]

Although support for extension methods was added in #1282, it appears there is some kind of parsing or quoting error which occurs when I try to define the * operator (curiously defining ** works fine)

For example running the following as a script:

extension (a: String)
  // definition of this operator (*) causes the issue
  def *(x: Int): String = "blarg"

  // only important to have a method following the one above
  def another = "blarg"

@

println("test" * 3)

(or alternatively running the 2 commands separately in a REPL) results in the following compile error

-- Error: /.../test.sc:44:2 -----------------------------
44 |  another
   |  ^^^^^^^
   |  named imports cannot follow wildcard imports
Compilation Failed

Adding braces does not help.

Running the commands together in a script works.

Tested with 2.5.4-22-4a9e6989, 2.5.4-26-9cd15abe.
