escaping for regexp ???

i've a regexp like that :

/.*#{name}$/ === path

however the variable "name" could, for example, in the form of :

"L2 Cache (per CPU)"

then, the string "name" might contain reserved chars for regexp,

i plan to escape them replacing "(" by "\\(" etc...

however i wonder if such a function for escaping reserved chars does
exists buit-in ???

notice i don't want to escape ".*" because i plan to use the wild card.
