Standard Library

`println`

Prints a value followed by a newline.

println("hello")    // prints a string
println(42)         // prints an integer
println(true)       // prints a boolean
println()           // prints a blank line

Backend implementation

Target	String	Int	Boolean
JVM	`System.out.println(String)`	`System.out.println(int)`	`System.out.println(boolean)`
DEX	`Ljava/io/PrintStream;->println(Ljava/lang/String;)V`	via `toString` + println	via `toString` + println
LLVM IR	`puts(str)`	`printf("%d\n", val)`	conditional `puts("true")`/`puts("false")`

Not yet available

The following standard library features are not yet implemented:

Feature	Blocked on
`print()` (no newline)	Straightforward to add
`readLine()`	I/O beyond println
`listOf`, `mutableListOf`	Generics, classes
`map`, `filter`, `fold`	Lambdas, generics
`to` (Pair creation)	Classes
`require`, `check`	Exception handling
`String.length`, `.substring()`	Method calls on classes
`Int.toString()`	Method calls on primitives
Math functions (`abs`, `max`, `min`)	Standard library binding
