+# This script works by using SnoopCompile to log compilations that take place
+# while running the examples on the GR backend. So SnoopCompile must be

+# some anonymous functions that not reproducible, but SnoopCompile PR #30
+# (which looks about to be merged) will ensure that anonymous functions are

+# keep only the keyword argument related anonymous functions by changing the
+# regex that SnoopCompile uses to detect anonymous functions to
