And an example that one should not blindly assume that
all programming languages follow the same conventions
about literals.

I actually already knew about such an example.

It is very very common that a language supports 123.45f for
32 bit FP and 123.45d for 64 bit FP and the language got some
standard for whether 123.45 default to 32 or 64 bit FP (aka
has an implicit f or d suffix).

Java:

public class WhatFP {
     public static void printType(Object o) {
         System.out.println(o.getClass().getName());
     }
     public static void main(String[] args) {
         printType(123.45f);
         printType(123.45d);
         printType(123.45);
     }
}

outputs:

java.lang.Float
java.lang.Double
java.lang.Double

works that way.

So one gets surprised when working with Groovy:

println(123.45f.class.name)
println(123.45d.class.name)
println(123.45.class.name)

outputs:

java.lang.Float
java.lang.Double
java.math.BigDecimal
