Postfix Type Declarations in Modern Programming Languages
Postfix type declarations, as seen in modern languages such as Go and Rust, place the type after the variable name—a style the author links to cultural naming conventions, arguing it highlights identifiers and can enhance readability after compilation, a practice historically validated by Pascal and Delphi.
Recent programming languages such as Go and Rust place the type after the variable name, unlike C‑style languages where the type precedes the name.
Examples: var b int (Go), let b:int32 = 100; (Rust), and int b = 100; (Java, C++, C#).
The author suggests cultural habits—Chinese name order versus Western name order—may affect developers' intuition about type placement.
Technically, postfix declarations highlight the variable name, which can improve readability once the compiler has verified the type.
Historically, languages like Pascal and Delphi also used postfix types, showing that both styles are viable.
