Subject: Re: [DRAFT] [RFC] Function autoloading

All,

I have updated the RFC to include 2 new benchmarks.

For normal class loading, this proposal shows at worst no change to loading
time. At best, it may actually improve it because at least one
zend_function_call is avoided (to spl_autoload_call).

For constants and function calls, the benchmark shows that the difference
is well within the margin of error for the test (considering variances of
5% to 10% were common in my running of the tests).

So hopefully this will dispel any worry about performance regressions in
currently defined cases.

The times where performance will take a hit, is with undefined functions
and constants. Today, an undefined function will fatal error, so this
performance hit would be 0, as it would enable something that's not
possible today.

The only regression can be where autoloaders are defined, and people are
relying on the legacy undefined constant behavior (which triggers an
E_NOTICE).
