To clarify Dan's answer about state variables (mostly, for myself).
If you run separate apps in the same process like these.
my $app1 = Test::Mojo->new('MyApp')->app;
my $app2 = Test::Mojo->new('MyApp')->app;
# now $app1->sqlite and $app2->sqlite is the same state variable.
You got two apps in the same process and they share the same state variable.

A lexical variable is still bound to a scope, even if it's the file
scope. If that scope is run again (such as creating another instance
of the same application) then that will have a separate instance of
that lexical variable. State variables are initialized once and shared
between any access for the rest of that process. It can't know what
outer scope you might have wanted to store it in. It can still be
useful but you have to make sure that's what you want.

Alternatively you can use 'state $sqlite = ' inside the helper
but this approach breaks the ability to run multiple separate
apps in the same process, because it will make one $sqlite per
whole process.

Could you expound on this problem? I thought state is just a
shortcut to closing over a lexical variable.
