Re^2: Scalar joining, concatenation, involving varying text

Thanks for the reply. Could you elaborate on the logic here. Does \ prevent interpolation until later evaluation? I just want to make sure I understand, \$$_allow us to substitute a variable name as the name for an implied variable within a loop.

`\` in string literals causes the next character as ordinary, so yes, it will will prevent interpolation: `$cow = 'moo!'; $_ = 'cow'; print("$cow"); # Prints moo! print("\$cow"); # Prints $cow print("\\\$cow"); # Prints \$cow print("\$$_"); # Prints $cow print(eval "$cow"); # Error executing "moo!". print(eval "\$cow"); # Prints moo! print(eval "\$$_"); # Prints moo!` [download] `qq{...}` is the same thing as `"..."`	[reply] [d/l] [select]

\

$cow = 'moo!';
$_ = 'cow';
print("$cow");          # Prints moo!
print("\$cow");         # Prints $cow
print("\\\$cow");       # Prints \$cow
print("\$$_");          # Prints $cow
print(eval "$cow");     # Error executing "moo!".
print(eval "\$cow");    # Prints moo!
print(eval "\$$_");     # Prints moo!
