==================== Summary ====================

Name: Compiler-eem.249
Author: eem

Ancestors: Compiler-eem.248

Simplify Parser>expression.  braceExpression is handled in
primaryExpression, as it should be.  The extra invocation in
expression is unnecessary, and harmlessly erroneous.

Fix snafu with Compiler-eem.248 (slightly less circuitous generation of methods with temp names).
