Data types

Type	Literal syntax	Notes
Integer	42	Whole numbers only — TLang has no floating-point type, by design.
String	"text"	Double-quoted. Concatenates with + against any other type.
Boolean	true / false	The only truthy/falsy values — conditions must evaluate to a boolean, or the interpreter raises a runtime error rather than coercing.
Function	define … taking …	First-class value; can be stored, passed, and called like any other.
