More diversity in the ecosystem, error-checking (having multiple compilers =
compiling the same source and checking the operation of the compiled output=
 against them is good for ensuring the standard is being implemented correc=

2: AdaCore's Pro edition, which does not.
3: FSF's edition which has runtime- and generic-exception [IIRC] to the GPL=
