public class let
extends Syntax
```
The Syntax transformer that re-writes the Scheme "let" primitive. This only handles standard "unnamed" let. The let macro in ../lib/let.scm handles named let as well.

    Description copied from class: Syntax
    
    Re-write an expression that is an "application" of this Syntax object.
    
    Overrides:
    
    rewrite in class Syntax
    
    Parameters:
    
    obj - the arguments to this "application" (i.e. the cdr of the macro/builtin invocation)
    
    tr - the Translator that provides context
    
    Returns:
    
    the re-written expression
  - maybeSetProcedure
```
protected void maybeSetProcedure(Declaration decl)
```
    Set the procedure flag of a declaration if binding a function property. This is used for FLET .vs. LET distinction, where settingProcedures is true for FLET, and false for LET.
    
    Parameters:
    
    decl - The declaration to possibly set the PROCEDURE flag.
