Yard

Yard is an funny programming language compiler and interpreter written in pure Rust.
Its a functional language, having no concept of classes or inheritance. Types are static and must be known at compile time.
It contains features such as:

1. a COMEFROM keyword (inverse goto)
2. a don't code block which never executes
3. no if. only unless, an inverted version of if. Meaning a block gets executed if the expression is false
4. three spaces start a single line comment
5. many ways of making comments: // comment, :REM: comment, # comment, -- comment -- cuz we can

Keywords

Syntax	Description	Example
Unless	Inverted if. Only executes the following block if the expression is false	unless 3 > 4 { // code block }
Loop	While(true)-Loop. Loops forever until either yield, ret, break are used. Loop take no boolean expression.	loop { // code block }
cont	Short form for “continue”. Jumps to the next iteration of a loop
break	Exits a loop immediately
yield	Returns from a function with an argument as return value	foo() = int { yield 4 }
ret	Short form for “return”. This keyword takes no argument and returns from a function. NOTE: if ret is used in a function with a return type, an error occurs.
please	Decides on runtime wether a block should be executed or not.	please { // code }

Example code

foo(bar: int, abc:int) = int {
    bar + abc
}

main {
    foo(4, 5)
}
