+# This chroma does a narrow, obscure but prestigious parsing of fpath+=( elem1
+# elem2 ... ) construct to provide *the* *future* contents of $fpath to
+# -autoload.ch, so that it can detect functions in those provided directories
+# `elem1', `elem2', etc. and highlight the functions with `correct-subtle'
+# instead of `incorrect-subtle'. Basically all thit is for command-lines like:
+#
+# % fpath+=( `pwd` ); autoload my-fun-from-PWD
+
+# Keep chroma-takever state meaning: until ; or similar (see $__arg_type below)
+# The 8192 sum takes care that the next token will be routed to this chroma
+(( next_word = 2 | 8192 ))
