+# Easier handling of supported compiler arguments
+
+A common pattern for handling multiple desired compiler arguments, was to
+test their presence and add them to an array one-by-one, e.g.:
+
+    warning_flags_maybe = [
+      '-Wsomething',
+      '-Wanother-thing',
+      '-Wno-the-other-thing',
+    ]
+    warning_flags = []
+    foreach flag : warning_flags_maybe
+      if cc.has_argument(flag)
+        warning_flags += flag
+      endif
+    endforeach
+    cc.add_project_argument(warning_flags)
+
+A helper has been added for the foreach/has_argument pattern, so you can
+now simply do:
+
+    warning_flags = [ ... ]
+    flags = cc.get_supported_flags(warning_flags)
