Subject: Make is_fun also work properly for Type CoreExprs.
X-Git-Url: https://git.stderr.nl/gitweb?a=commitdiff_plain;ds=sidebyside;h=2ca7af8f94b990f13d9ef299a889e2ad591759a2;p=matthijs%2Fmaster-project%2Fc%CE%BBash.git

Make is_fun also work properly for Type CoreExprs.

Previously, this would generate some debug output from exprType, which
isn't properly defined for Type expressions.
