yep, pretty much.

although taking the destination type into account could help with things 
like preserving precision by promoting types early, or help avoid 
unnecessary warnings/errors in a few other cases (for example, lessening 
the need for suffixes on numerical constants, ...), it is less certain 
in other cases, namely where the interpretation could have a potentially 
significant influence on language semantics.
