This is pretty benign, but since somebody reported it:

apm@mara:~/projects/snytt$ scala210
Welcome to Scala version 2.10.4 (OpenJDK 64-Bit Server VM, Java 1.7.0_65).
Type in expressions to have them evaluated.
Type :help for more information.

scala> (1 to 9).toList match { case List(`_`*) => true }
res0: Boolean = true
