Dynamic languages ​​Vs Static languages ​​(can these two be together in the same place)

Programming languages

grouped into 2 main classes "Dynamic" and "Static". - It is always the case that the programming language is in one of them, and not both, I mean, can the language be dynamic and static at the same time?

The difference between static and dynamic language is rather ambiguous, since it can relate to many different (more or less suitable) criteria. I will try to answer for each case:

Interpretation / Compilation

, . , .

  • Haskell (GHC/GHCI/Hugs)
  • ++ (g++/Ch)
  • F #

(.NET).

( ) . . # dynamic, VB Explicit/Strict off Boo. . (System.Object) - , .

Java .NET.

Objective-C - . C, C . "" ( , id). Objective-C, , id. , NSArray id, :

NSMutableArray *a = [NSMutableArray arrayWithObject:@"I am a string"];
NSNumber *n = [a objectAtIndex:0]; //assigning a string to a number!

NSNumber *n = @"I am a string" .

Therefore, I suppose that a language can be both dynamic and static. In particular, by checking statically type and supporting interactive evaluation.
