For loops _are_ a thing, but only in the macro context: [Macros - Crystal](https://crystal-lang.org/reference/1.9/syntax_and_semantics/macros/index.html#iteration). The primary reason for the difference is macros are somewhat special in that they need access to the program itself for code generation reasons.

P.S. Could also do like:

```crystal
1.upto 10 do |i|
  puts i
end

```
