About DLR:
The underlying DLR uses the same static type system as the CLR, but the DLR defines a proxy layer on top of the CLR type system. In this proxy layer, the DLR manages its own type system ing, in addition, the dynamic distribution mechanism of this proxy layer is used to achieve dynamic method selection, while the other main function of DLR is dynamic.CodeThe Dynamic Language Interpreter is used in combination with the abstract syntax tree of DLR. First, the interpreter of the Dynamic Language performs lexical analysis, syntax analysis, and Semantic Analysis on the dynamic language script, then, the abstract syntax tree of DLR is generated based on the semantic analysis results, and then compiled and executed.
