Do you mean this ?Currently what I use is the `*` operator on lists :
```
print([
3,
]
+ ([never_called()] if False else [])
+ [
2,
]
+ ([5] if True else [])
+ [
4
]) # => [3, 2, 5, 4]
```
(put the whitespaces where you want)
And if the call to `never_called()` is not important (no need for
shortcircuit) :
```
print([
3,
]+ [
never_called()
] * False + [
2,
] + [
5
] * True + [
4
]) # => [3, 2, 5, 4]
```
(put the whitespaces where you want)
You could do things like L = [4,5,2] + ['hello', world'] * (a == 5) + [8,9]
Of course, that's not as optimised as :
L = []
L += [4,5,2]
if a == 5: L += ['hello', world']
L += [8,9]
