A new local scope is introduced by most code blocks (see above [table](@ref man-scope-table) for a
complete list). Some programming languages require explicitly declaring new variables before using
complete list). If such a block is inside another local scope, this will be a "nested" local scope
that contains existing locals — even if the code where they are defined is written after the nested block.
Some programming languages require explicitly declaring new variables before using
them. Explicit declaration works in Julia too: in any local scope, writing `local x` declares a new
local variable in that scope, regardless of whether there is already a variable named `x` in an
outer scope or not. Declaring each new local like this is somewhat verbose and tedious, however, so
