Do remember that Slang is merely a pidjin that makes it relatively
simple to write C code within Squeak in order that we can
a) simulate the vm to try out new ideas more easily and debug them
within our favourite debugger
b) transliterate the code to (not terribly good) C code for compilation
If you write
> oop := interpreterProxy instantiateClass: MyClass indexableSize: 0.
... then it will
a) in simulation it will do exactly what you might expect - send
#fooble to oop. Since oop is probably an integer standing in as an
object pointer (haven't done this in ages) you might be surprised at
b) when transliterating it will convert the 'oop fooble' to 'sqInt
fooble(sqInt oop);' - modulo the differences between declaration and
It doesn't do anything clever at all.
