valueOf: takes a Smalltalk object and returns a 32-bit C value.
IntegerFor: takes a 32-bit C value and answers a Smalltalk object.
I find these natural :)

Things I *hate* are nasty gotchers in Slang like
        self sizeof: #sqLong
which translates to
You have to write
        self sizeof: #sqLong asSymbol
to get

I'd fix this but IIRC there are plugins that use this.  Ho hum.  Some time
we need to rationalize Slang and throw out some of the more evil traps such
as the above.

These methods along with other xxxIntegerFor: and xxxValueOf:

Why not create some more comprehensible aliases for your own use and get
e.g. Slang to translate them to the form you find hard to distinguish?
