It's not "getting to" a "string" value but to a "string t" value, which 
is an abbreviation for "float". The value has type "float", but the user 
requires type "string t", so the compiler unifies "float" and "string t" 
which is actually "float" so it's ok, and then the compiler gives the 
type requested by the user to the value, i.e., "string t".

Well, at least, this is how I understand this :)
