withdrawn from this effort. To cater for early adopters, there is optional
support in Vim for syntax related preview features that are implemented. You
can request it by specifying a list of preview feature numbers as follows: >
- :let g:java_syntax_previews = [455]
+ :let g:java_syntax_previews = [455, 476]
The supported JEP numbers are to be drawn from this table:
`430`: String Templates [JDK 21]
`455`: Primitive types in Patterns, instanceof, and switch
+ `476`: Module Import Declarations
Note that as soon as the particular preview feature will have been integrated
into the Java platform, its entry will be removed from the table and related
