Transform static immutable string array to tuple.

[realhet via Digitalmars-d-learn]

Hello,

Is there a better way to transform a string array to a tuple or 
to an AliasSeq?

```
mixin(customSyntaxPrefixes.format!`tuple(%(%s,%))`)
```

I'd like to use this as variable length arguments passed to the 
startsWith() std function (as multiple needles).
