Incorrect error message for undeclared struct field

[raptor-666]

When using structs in KSP scripts, an error occurs indicating that a struct field has not been declared, even though it has been correctly declared.

Steps to Reproduce:

1. Create a new script using the following code:

   on init
   struct simple_struct
       declare int_var
       declare ~float_var
   end struct
   
   declare &simple_struct new_structs[2]
   new_structs[0].int_var := 1
   new_structs[0].float_var := -1.0
   end on

2. Run the script in Sublime Text with the SublimeKSP plugin.

Expected Behavior: The code should execute without errors since the 'float_var' field is correctly declared in the 'simple_struct' struct.

Actual Behavior: An error is thrown:

new_structs.float_var has not been declared! (line 16) new_structs(0).float_var := 1.0 main script: 9

Screenshot:

Additional Information: The error occurs only for fields declared with a tilde ('~') when a struct array is declared. Fields declared without a tilde work correctly.

I suppose structs feature was done before we had reals in KSP and so was never adapted to work with them...
