In computer languages, there are very few that are structurally different.
FORTRAN is like COBOL, which is like Pascal, which is like BASIC, which is like ADA, which is like …
Forth is not like those above. Nor is APL or Lisp.
Assembly languages can be used in structured ways, just like FORTRAN, COBOL, Pascal, and many others. It requires the discipline to use if not condition jump skip_label; do stuff in condition; skip_label:. The actual programming logic stays the same.
The two computer languages I dislike the most are PHP and Python. Both because they are weakly typed.
In a strongly typed language, you declare a variable’s type before you use it. The type of the variable is immutable for its lifetime.
In other words, if you declare a variable of being of type integer and then attempt to assign a string to it, it will barf on you during compilation.
In PHP, all variables look the same, any variable can hold any type at any moment. The type can change from line to line. And the language will do implicit type casting. It is hateful.
Python has all the same characteristics I hate in PHP, with the added hateful feature of using indentation instead of begin-and markers for blocks.
I’m lucky that Python has an optional typing capability, which I use consistently. The optional part is a pain when I want to use a module that has no typing information. When that happens, I need to create my own typing stub.
But the worse part of all of this is that they get jumbled together in my head. How many entries in an array? In PHP, that is determined by the count() function, in Python it is the len() function.
In Python, the dot (.) is used to access methods and attributes of objects. In PHP, it is the concatenation symbol.
I am tired of writing Python in my PHP files and I dread switching back to Python because I know my fingers will mess things up.
