#17 Conversion of pointer parameters into references

[Markus Elfring]

I suggest to convert a parameter like "i" (function "compile") and "Go" (function "find") from a pointer to a reference so that further tests can be omitted because the intended check can be performed at compile time.

Can such an interface design adjustment be applied on other places in the source code, too?
