For older people like me, who began with Basic because the commodore vic20 and 64 we're using a basic interface, there are some key languages missing:
- assembly: the language real programmer had to use to get things moving, of course specific to a given processor hardware,
- Pascal, that was not only the best structured language but the native language for acces to the MacOS ROM functions (of course you could access them with any languages, but the doc was in Pascal)
- I personally wrote my larges software in Matlab, as a scientific language, but many colleagues were strong in Mathematica.
But real men use PERL, of course.
