☑ cool new feature
☑ could help many users! ("nobody" is using expression handling? - maybe ... why?)
☑ removes something that feels like a „bug“
☐ nice to have
☐ nobody needs it
What inspired this wish list request?
In JSL, Expr() is used for 2 purposes:
- "it is here()" inside of Eval Expr()
- I protect you() - to protect the content from being evaluated
Unfortunately, Eval Expr() is happy with the first Expr() and evaluates it.
This restricts the flexibility with which users can write nested expressions - see:

TS-00235515 TS-00235798 |
What is the improvement you would like to see?
Add 2 new functions to JMP for the 2 meanings of Expr():
- "it is here() *) " inside of Eval Expr()
- I protect you() *) - to protect the content from being evaluated
*) please use the comments to suggest optimized function names?
- as short as possible
- as "telling" as possible [Name Expr() is the ideal name for Name Expr() - for German speakers ...]
Together with the [legacy] Expr(), they should allow the user to write code much easier in JSL.
e.g.
Eval Expr(protect( .... Expr(expression to evaluate) ...) ...)
in the sense of
Eval Expr(protect( .... it is here(expression to evaluate) ...) ...)
Why is this idea important?
the dual-use of Expr() it is harmful and makes code fragile and complicated.
Using separate names for the 2 meanings will fix the issue.
