A modern programming language that makes developers happier.

kotlinlang

```
val suggested = availableVars.map { it.canonicalName }.minBy { getLevenshteinDistance(it, desiredName) }
val footer = if(suggested != null) " (did you mean '$suggested'?)" else ""
reportSemanticError("no such $mode variable '$desiredName'$footer")
```

becomes

```
val template = ST("no such $mode variable '$desiredName'&lt;if(suggested)&gt; (did you mean '&lt;suggested&gt;')&lt;endif&gt;").apply{
  addSymbol("suggested", availableVars.map { it.canonicalName }.minBy { getLevenshteinDistance(it, desiredName) })
}
```

under string template which _could_ be something like

```
val suggested = availableVars.map { it.canonicalName }.minBy { getLevenshteinDistance(it, desiredName) }
reportSemanticError("no such $mode variable '$desiredName'${if(suggested != null)} (did you mean $suggested?)${endif}")
```

if kotlin was willing to tolerate `endif`, which is anathama to many C-like languages
