Fixes #329
Considering that it wasn't previously possible to shadow variables. Then this qualifies as a non-breaking change, as it only extends new functionality.
initialized
toLocalMeta
In short, if a
LocalMeta
isinitialized
then any subsequent{% let ... %}
shadows and generates a new variable. The variable is literally redefined byinsert
ing a new one. Thereby making it possible to e.g. initialize and shadow in multiple nested branches.To be consistent with Rust,
{% let (a, b) = ... %}
always shadows, and can't be used to assign (which it couldn't before either.)
