Yes, it's highly possible that the pattern environment doesn't allow the use
of functions from the language, or perhaps core functions.
You can look at map_metadata which is now the main function for rewriting
metadata. rewrite_metadata is now written using this one in utils.liq:
def rewrite_metadata(l,~insert_missing=true,
~update=true,~strip=false,
s)
# We don't need to return all values, since
# map_metadata only update returned values.
# So, we simply apply all rewrite rules !
def map(m)
def apply(x)
label = fst(x)
value = snd(x)
(label,value % m)
end
list.map(apply,l)
end
map_metadata(map,insert_missing=insert_missing,
update=update,strip=strip,s)
end
