Another reason not to use File is because it is slower as it is unbuffered.
For the following file
$ file test.png
test.png: PNG image data, 950 x 936, 8-bit/color RGBA, non-interlaced
$ ls -la test.png
-rw-r--r--@ 1 sven staff 241773 Nov 11 13:39 test.png
I get
[ ImageReadWriter formFromFileNamed: 'test.png' ] bench.
"'8.725 per second'"
[ ImageReadWriter formFromStream: 'test.png' asFileReference binaryReadStream ]
bench.
"'8.914 per second'"
[ ImageReadWriter formFromStream: (File named: 'test.png') readStream ] bench.
"'6.023 per second'"
By preventing the auto detection of the type and the subclass lookup, we can
improve a little bit more.
[ PNGReadWriter formFromStream: 'test.png' asFileReference binaryReadStream ]
bench.
"'9.113 per second'"
