if checking for/getting a value from a hashmap requires all

besides, i do use the language features in my project,
templates and mixins to solve larger problems, it's great, and
reason why i picked D
An alternative would be yet another template wrapper for get
value that takes a dictionary an a lambda and call that lambda
only if value is present, this means you no longer do the if, but
rather a "cryptic" call like in some other languages.
pseudo code:
```d
// helper function
void withKey(V,K,L)(V[K] dict, K key, lazy L dostuff) {
if (auto value = dict.get(K)) {
doStuff(*value);
}
}
// usage
string[int] counters;
counters["foo"] = 42;
counters.withKey("foo", (value) {
assert(value == 42);
});
```
