How can Pyth be improved? Pyth is in ongoing development, meaning that new features are being added all the time.

I want to make Pyth a better langauge, so I'd like to know what features people are looking for.

This is the place the post ideas you have for making Pyth better.

In your answer, please state:


What you'd like to see changed/added.
An example usage of the change.


I'll comment if I'm planning to implement the suggestion.

Please check if the idea you want to suggest has already been suggested. Upvote ideas you'd like implemented.



Implemented suggestions:


Eval string in Pyth, as .v
More Regex operations
Apply While as .W
Nested Loops and More Lambdas (They use the same mechanism underneath)
Flatten nested lists as .n




This was on topic as per this meta question when I posted the question, it is no longer clear.
Nested loops
If you want to nest for loops, you currently have to waste a byte for using F&lt;var&gt;&lt;seq&gt; inside a V&lt;seq&gt; or vice versa. I'd love to have the same thing as with lambdas, where the variable used for the loop would change when nesting loops.
