Name before type: why 'age int' is better than 'int age'
benhoyt.com/writings/name-before-type/benhoyt.comName before type: why 'age int' is better than 'int age'A variable's name is more important than its type, so the name should be more prominent and come first in declarations.

Hard disagree. Is that a joke? Type is far More important than name. Just ask the compiler.

a lot of modern languages explicitly disagree, eg Kotlin and Rust

I think that’s so type inference can work by just omitting the type, instead of having to use “var” or “auto” in front of the variable name

not precisely. Rust has let mut and Kotlin has val; ie the member layout and the mutability are treated differently, since those languages have mutability rules.
this is a circular argument anyway. the language designers could have figured out a way to do type inference like, eg, Java, but, again, explicitly chose not to.

let foo : String;
In rust the variable name is before its type (which can be omitted if the compiler can infer it).
