But, as already said, don't. eval in this context is definitely worse than using a hash, in almost every regard.

Why use `eval` to do `if do { no strict 'refs'; $$string };` [download]	[reply] [d/l] [select]

Why use `eval` ...because the OP used lexical variables. Symbolic references (`$$string`) only work with package variables.	[reply] [d/l] [select]
