You can assign items of a sequence to a slice of the same length:

or of any length in phix, eg: 

string s = "fed" 
s[2..2] = "easte"   -- "e"->"easte", or 
--s[2..1] = "east"  -- ie "f" & x & "ed" 
--s[3..2] = "aste"  -- ie "fe" & x & "d" 
?s 
-- s is now "feasted" 
-- the two alternatives insert/replace an empty slice 
 
s[2..6] = "e"   -- "easte" -> "e" 
--s[2..5] = ""  -- or "east" -> "" 
--s[3..6] = ""  -- or "aste" -> "" 
?s 
--s is now "fed"
