# Tests for target-local variables, such as ${.TARGET} or $@.
# TODO: Implementation
# Ensure that the name of the variable is exactly the given one.
# The variable "@" is an alias for ".TARGET", so the implementation might
# canonicalize these aliases at some point, and that might be surprising.
# This aliasing happens for single-character variable names like $@ or $<
# (see VarFind, CanonicalVarname), but not for braced or parenthesized
# expressions like ${@}, ${.TARGET} ${VAR:Mpattern} (see Var_Parse,
# ParseVarname).
