"A Simple Scheme In 20 Minutes"
When I went to university, my degree was deliberately steered away from the esoterica of compilers and interpreters. My degree and financial backing was predicated on my getting "practical" programming skills, so I took classes in COBOL, Fortran, ADA, SQL, Accounting, and similar subjects intended to make me a "financial products" programmer.
The Internet came along and gave me a much more interesting career, but now it's time to rectify the shortcoming of my education and study programming languages themselves. This is a "My First Programming Language." Just trying to keep my skills up.
It only has three special forms: 'define', 'lambda', and 'if'. It understands addition, subtraction, multiplication, division, and equality for the purposes of the 'if' special form, although it's clearly treating arithmetic as 'special forms' for the purpose of doing the math. It's good enough to handle lexical scoping and recursion, and it handles basic integer arithmetic. There is a bug is the lexer such that symbols that start with a numeral won't be read right, but I'm too lazy to fix it.
It has no macros. Sorry about that.
