-- When generating javasript from idris, it is possible that the same name may appear in
|
|
-- different clauses when translating cases from Idris. To avoid a javascript syntax error
|
|
-- from occuring due to duplicate declations, each case clause is wrapped in brackets
|
|
-- to create unique block scopes.

|
|
-- Without wrapping in a block, the test error may look like the following:
|
|
-- syntax001/build/exec/_tmp_node.js:39
|
|
-- const x = ({h:1});
|
|
-- ^
|
|
-- SyntaxError: Identifier 'x' has already been declared
