Same here...
But, I wonder. With modern optimizing compilers doing almost what they
want with the original source code, I'm quite sure some semantic
optimiser will replace parts of codes by goto's anyway. So why would it
ever be necessary to worry about optimising the source code with
'spaghetti' code, as we are shifting the responsability for optimising
execution to the compiler writers anyway?
If fact, if the optimiser is good, spaghetti (goto-)programs and 'nice'
code should generate the same executable anyway, shouldn't they? So,
doesn't it make sense to try and make the source as readable as possible?
gotos make life for optimizing steps based on data flow information very
hard, so using while, repeat etc. makes also life for an optimizer easier.
