[fpc-devel] State of SSE/AVX intrinsics

I'm not totally certain what the design intentions are with new language
features - back in the 90s, a friend told me Pascal (actually Delphi
2.0) has the simplicity of Visual Basic but the power of Visual C++.
I'm not sure how true that is, but it's what's inspired me. Going by
that, I would like new or adapted features to be relatively easy to use
while still being efficient.
A global option, like a preprocessor directive or command line option,
feels a bit dangerous and can easily introduce unexpected bugs if it's
left out, so an explicit optional parameter (e.g. GetMem(AlignedVector,
4096, 64);) would feel like the way to go.

P.S. The only exception to an 'easy to use' feature in my eyes is inline
assembly, which I've always seen as "it's there if you want to use it".
