This file contains invisible Unicode characters

This file contains invisible Unicode characters that are indistinguishable to humans but may be processed differently by a computer. If you think that this is intentional, you can safely ignore this warning. Use the Escape button to reveal them.

# This file contains tests for the tclProc.c source file. Tests appear in the
# same order as the C code that they test. The set of tests is currently
# incomplete since it includes only new tests, in particular tests for code
# changed for the addition of Tcl namespaces. Other procedure-related tests
# appear in other test files such as proc-old.test.
#
# Sourcing this file into Tcl runs the tests and generates output for errors.
# No output means no errors were found.
